DESCRIPTION

       Beginning with Shorewall 5.1.0, the shorewall utility is used to control the Shoreline
       Firewall (Shorewall), Shorewall Firewall 6 (Shorewall6), Shorewall Firewall Lite
       (Shorewall-lite) and Shorewall Firewall 6 Lite (Shorewall6-lite). The utility may be
       accessed under four different names:

       shorewall
           Controls the Shorewall configuration when Shorewall is installed. If Shorewall is not
           installed, the shorewall command controls Shorewall-lite if it is installed. If
           neither Shorewall nor Shorewall-lite is installed, the shorewall command controls
           Shorewall6-lite if it is installed.

       shorewall6
           The shorewall6 command controls Shorewall6 when Shorewall6 is installed.

       shorewall-lite
           The shorewall-lite command controls Shorewall-lite when Shorewall-lite is installed.

       shorewall6-lite
           The shorewall6-lite command controls Shorewall6-lite when Shorewall6-lite is
           installed.

       Prior to Shorewall 5.1.0, these four commands were implemented as four separate program,
       each of which controlled only a single firewall package. This manpage serves to document
       both the Shorewall 5.1 and Shorewall 5.0 CLI.

OPTIONS

       The trace and debug options are used for debugging. See
       http://www.shorewall.net/starting_and_stopping_shorewall.htm#Trace[1].

       The nolock option prevents the command from attempting to acquire the Shorewall lockfile.
       It is useful if you need to include shorewall commands in /etc/shorewall/started.

       Other options are:

       -4
           Added in Shorewall 5.1.0. Causes the command to operate on the Shorewall configuration
           or the Shorewall-lite configuration. It is the default when either of those products
           is installed and when the command is shorewall or shorewall-lite.

       -6
           Added in Shorewall 5.1.0. Causes the command to operate on the Shorewall6 or
           Shorewall6-lite configuration. It is the default when only Shorewall6-lite is
           installed and when the command is shorewall6 or shorewall6-lite.

       -l
           Added in Shorewall 5.1.0. Causes the command to operate on either Shorewall-lite or
           Shorewall-6 lite and is the default when Shorewall is not installed or when the
           command is shorewall-lite or shorewall6-lite.

           With all four firewall products (Shorewall, Shorewall6, Shorewall-lite and
           Shorewall6-lite) installed, the following table shows the correspondence between the
           name used to invoke the command and the shorewall command with the above three
           options.

           Table 1. All four products installed
           The next table shows the correspondence when only Shorewall-lite and Shorewall6-lite
           are installed.

           Table 2. Only Shorewall-lite and Shorewall6-lite installed
       -v[verbosity]
           Alters the amount of output produced by the command. If neither the -v nor -q option
           are specified, the amount of output is determined by the VERBOSITY setting in
           shorewall.conf[2](5) (shorewall6.conf[3](5)).

           When no verbosity is specified, each instance of this option causes 1 to be added to
           the effective verbosity. When verbosity (-1,0,1 or 2) is given, the command is
           executed at the specified VERBOSITY. There may be no white-space between -v and the
           verbosity.

       -q
           Alters the amount of output produced by the command. If neither the -v nor -q option
           are specified, the amount of output is determined by the VERBOSITY setting in
           shorewall.conf[2](5) (shorewall6.conf[3](5)).

           Each instance of this option causes 1 to be subtracted from the effective verbosity.

       -t
           Causes all progress messages to be timestamped.

COMMANDS

       The available commands are listed below.

       add { interface[:host-list]... zone | zone host-list }
           Adds a list of hosts or subnets to a dynamic zone usually used with VPN's.

           The interface argument names an interface defined in the shorewall-interfaces[4](5)
           (shorewall6-interfaces[5](5))file. A host-list is comma-separated list whose elements
           are host or network addresses..if n .sp
               Caution
               The add command is not very robust. If there are errors in the host-list, you may
               see a large number of error messages yet a subsequent shorewall show zones command
               will indicate that all hosts were added. If this happens, replace add by delete
               and run the same command again. Then enter the correct command.

           Beginning with Shorewall 4.5.9, the dynamic_shared zone option
           (shorewall-zones[6](5),shorewall6-zones[7](5)) allows a single ipset to handle entries
           for multiple interfaces. When that option is specified for a zone, the add command has
           the alternative syntax in which the zone name precedes the host-list.

       allow address
           Re-enables receipt of packets from hosts previously blacklisted by a blacklist, drop,
           logdrop, reject, or logreject command.

       blacklist address [ option ... ]
           Added in Shorewall 5.0.8 and requires DYNAMIC_BLACKLIST=ipset.. in
           shorewall.conf[2](5). Causes packets from the given host or network address to be
           dropped, based on the setting of BLACKLIST in shorewall.conf[2](5). The address along
           with any options are passed to the ipset add command.

           If the disconnect option is specified in the DYNAMIC_BLACKLISTING setting, then the
           effective VERBOSITY determines the amount of information displayed:

           ·   If the effective verbosity is > 0, then a message giving the number of conntrack
               flows deleted by the command is displayed.

           ·   If the effective verbosity is > 1, then the conntrack table entries deleted by the
               command are also displayed.

       call function [ parameter ... ]
           Added in Shorewall 4.6.10. Allows you to call a function in one of the Shorewall
           libraries or in your compiled script. function must name the shell function to be
           called. The listed parameters are passed to the function.

           The function is first searched for in lib.base, lib.common, lib.cli and lib.cli-std.
           If it is not found, the call command is passed to the generated script to be executed.

       check [-e] [-d] [-p] [-r] [-T] [-i] [directory]
           Not available with Shorewall[6]-lite.

           Compiles the configuration in the specified directory and discards the compiled output
           script. If no directory is given, then /etc/shorewall is assumed.

           The -e option causes the compiler to look for a file named capabilities. This file is
           produced using the command shorewall-lite show -f capabilities > capabilities on a
           system with Shorewall Lite installed.

           The -d option causes the compiler to be run under control of the Perl debugger.

           The -p option causes the compiler to be profiled via the Perl -wd:DProf command-line
           option.

           The -r option was added in Shorewall 4.5.2 and causes the compiler to print the
           generated ruleset to standard out.

           The -T option was added in Shorewall 4.4.20 and causes a Perl stack trace to be
           included with each compiler-generated error and warning message.

           The -i option was added in Shorewall 4.6.0 and causes a warning message to be issued
           if the current line contains alternative input specifications following a semicolon
           (";"). Such lines will be handled incorrectly if INLINE_MATCHES is set to Yes in
           shorewall.conf[2](5) (shorewall6.conf[3](5)).

       clear [-f]
           Clear will remove all rules and chains installed by Shorewall. The firewall is then
           wide open and unprotected. Existing connections are untouched. Clear is often used to
           see if the firewall is causing connection problems.

           If -f is given, the command will be processed by the compiled script that executed the
           last successful start, restart or reload command if that script exists.

       close { open-number | source dest [ protocol [ port ] ] }
           Added in Shorewall 4.5.8. This command closes a temporary open created by the open
           command. In the first form, an open-number specifies the open to be closed. Open
           numbers are displayed in the num column of the output of the shorewall show opens
           command.

           When the second form of the command is used, the parameters must match those given in
           the earlier open command.

           This command requires that the firewall be in the started state and that
           DYNAMIC_BLACKLIST=Yes in shorewall.conf (5)[2].

       compile [-e] [-c] [-d] [-p] [-T] [-i] [ directory ] [ pathname ]
           Not available with shorewall[6]-lite.

           Compiles the current configuration into the executable file pathname. If a directory
           is supplied, Shorewall will look in that directory first for configuration files. If
           the pathname is omitted, the file firewall in the VARDIR (normally
           /var/lib/shorewall/) is assumed. A pathname of '-' causes the compiler to send the
           generated script to it's standard output file. Note that '-v-1' is usually specified
           in this case (e.g., shorewall -v-1 compile -- -) to suppress the 'Compiling...'
           message normally generated by /sbin/shorewall.

           When -e is specified, the compilation is being performed on a system other than where
           the compiled script will run. This option disables certain configuration options that
           require the script to be compiled where it is to be run. The use of -e requires the
           presence of a configuration file named capabilities which may be produced using the
           command shorewall-lite show -f capabilities > capabilities on a system with Shorewall
           Lite installed

           The -c option was added in Shorewall 4.5.17 and causes conditional compilation of a
           script. The script specified by pathname (or implied if pathname is omitted) is
           compiled if it doesn't exist or if there is any file in the directory or in a
           directory on the CONFIG_PATH that has a modification time later than the file to be
           compiled. When no compilation is needed, a message is issued and an exit status of
           zero is returned.

           The -d option causes the compiler to be run under control of the Perl debugger.

           The -p option causes the compiler to be profiled via the Perl -wd:DProf command-line
           option.

           The -T option was added in Shorewall 4.4.20 and causes a Perl stack trace to be
           included with each compiler-generated error and warning message.

           The -i option was added in Shorewall 4.6.0 and causes a warning message to be issued
           if the current line contains alternative input specifications following a semicolon
           (";"). Such lines will be handled incorrectly if INLINE_MATCHES is set to Yes in
           shorewall.conf[2](5) (shorewall6.conf[3](5)).

       delete { interface[:host-list]... zone | zone host-list }
           The delete command reverses the effect of an earlier add command.

           The interface argument names an interface defined in the shorewall-interfaces[4](5)
           (shorewall6-interfaces[5](5) file. A host-list is comma-separated list whose elements
           are a host or network address.

           Beginning with Shorewall 4.5.9, the dynamic_shared zone option (shorewall-zones[6](5),
           shorewall6-zones[8](5)) allows a single ipset to handle entries for multiple
           interfaces. When that option is specified for a zone, the delete command has the
           alternative syntax in which the zone name precedes the host-list.

       disable { interface | provider }
           Added in Shorewall 4.4.26. Disables the optional provider associated with the
           specified interface or provider. Where more than one provider share a single network
           interface, a provider name must be given.

           Beginning with Shorewall 4.5.10, this command may be used with any optional network
           interface.  interface may be either the logical or physical name of the interface. The
           command removes any routes added from shorewall-routes[9](5)
           (shorewall6-routes[10](5))and any traffic shaping configuration for the interface.

       drop address
           Causes traffic from the listed addresses to be silently dropped. This command requires
           that the firewall be in the started state and that DYNAMIC_BLACKLIST=Yes in
           shorewall.conf (5)[2].

       dump  [-x] [-l] [-m] [-c]
           Produces a verbose report about the firewall configuration for the purpose of problem
           analysis.

           The -x option causes actual packet and byte counts to be displayed. Without that
           option, these counts are abbreviated.

           The -m option causes any MAC addresses included in Shorewall log messages to be
           displayed.

           The -l option causes the rule number for each Netfilter rule to be displayed.

           The -c option causes the route cache to be dumped in addition to the other routing
           information.

       enable { interface | provider }
           Added in Shorewall 4.4.26. Enables the optional provider associated with the specified
           interface or provider. Where more than one provider share a single network interface,
           a provider name must be given.

           Beginning with Shorewall 4.5.10, this command may be used with any optional network
           interface.  interface may be either the logical or physical name of the interface. The
           command sets /proc entries for the interface, adds any route specified in
           shorewall-routes[9](5) (shorewall6-routes[10](5)) and installs the interface's traffic
           shaping configuration, if any.

       export [ directory1 ] [ user@]system[:directory2 ]
           Not available with Shorewall[6]-lite.

           If directory1 is omitted, the current working directory is assumed.

           Allows a non-root user to compile a shorewall script and stage it on a system
           (provided that the user has access to the system via ssh). The command is equivalent
           to:

                   /sbin/shorewall compile -e directory1 directory1/firewall &&\
                   scp directory1/firewall directory1/firewall.conf [user@]system:[directory2]

           In other words, the configuration in the specified (or defaulted) directory is
           compiled to a file called firewall in that directory. If compilation succeeds, then
           firewall and firewall.conf are copied to system using scp.

       forget [ filename ]
           Deletes /var/lib/shorewall/filename and /var/lib/shorewall/save. If no filename is
           given then the file specified by RESTOREFILE in shorewall.conf[2](5)
           (shorewall6.conf[3](5)) is assumed.

       help
           Displays a syntax summary.

       hits [-t]
           Generates several reports from Shorewall log messages in the current log file. If the
           -t option is included, the reports are restricted to log messages generated today. Not
           available with Shorewall6[-lite].

       ipcalc { address mask | address/vlsm }
           Ipcalc displays the network address, broadcast address, network in CIDR notation and
           netmask corresponding to the input[s]. Not available with Shorewall6[-lite].

       iprange address1-address2
           Iprange decomposes the specified range of IP addresses into the equivalent list of
           network/host addresses. Not available with Shorewall6[-lite].

       iptrace iptables match expression
           This is a low-level debugging command that causes iptables TRACE log records to be
           created. See iptables(8) for details.

           The iptables match expression must be one or more matches that may appear in both the
           raw table OUTPUT and raw table PREROUTING chains.

           The log message destination is determined by the currently-selected IPv4 or IPv6
           logging backend[11].

       list
           list is a synonym for show -- please see below.

       logdrop address
           Causes traffic from the listed addresses to be logged then discarded. Logging occurs
           at the log level specified by the BLACKLIST_LOGLEVEL setting in shorewall.conf[2] (5)
           (shorewall6.conf[3](5)). This command requires that the firewall be in the started
           state and that DYNAMIC_BLACKLIST=Yes in shorewall.conf (5)[2].

       logwatch [-m] [ refresh-interval ]
           Monitors the log file specified by the LOGFILE option in shorewall.conf[2](5)
           (shorewall6.conf[3](5)) and produces an audible alarm when new Shorewall messages are
           logged. The -m option causes the MAC address of each packet source to be displayed if
           that information is available. The refresh-interval specifies the time in seconds
           between screen refreshes. You can enter a negative number by preceding the number with
           "--" (e.g., shorewall logwatch -- -30). In this case, when a packet count changes, you
           will be prompted to hit any key to resume screen refreshes.

       logreject address
           Causes traffic from the listed addresses to be logged then rejected. Logging occurs at
           the log level specified by the BLACKLIST_LOGLEVEL setting in shorewall.conf[2] (5),
           (shorewall6.conf[3](5)). This command requires that the firewall be in the started
           state and that DYNAMIC_BLACKLIST=Yes in shorewall.conf (5)[2].

       ls
           ls is a synonym for show -- please see below.

       noiptrace iptables match expression
           This is a low-level debugging command that cancels a trace started by a preceding
           iptrace command.

           The iptables match expression must be one given in the iptrace command being canceled.

       open source dest [ protocol [ port ] ]
           Added in Shorewall 4.6.8. This command requires that the firewall be in the started
           state and that DYNAMIC_BLACKLIST=Yes in shorewall.conf (5)[2]. The effect of the
           command is to temporarily open the firewall for connections matching the parameters.

           The source and dest parameters may each be specified as all if you don't wish to
           restrict the connection source or destination respectively. Otherwise, each must
           contain a host or network address or a valid DNS name.

           The protocol may be specified either as a number or as a name listed in
           /etc/protocols. The port may be specified numerically or as a name listed in
           /etc/services.

           To reverse the effect of a successful open command, use the close command with the
           same parameters or simply restart the firewall.

           Example: To open the firewall for SSH connections to address 192.168.1.1, the command
           would be:

                   shorewall open all 192.168.1.1 tcp 22

           To reverse that command, use:

                   shorewall close all 192.168.1.1 tcp 22

       reenable{ interface | provider }
           Added in Shorewall 4.6.9. This is equivalent to a disable command followed by an
           enable command on the specified interface or provider.

       reject address
           Causes traffic from the listed addresses to be silently rejected. This command
           requires that the firewall be in the started state and that DYNAMIC_BLACKLIST=Yes in
           shorewall.conf (5)[2].

       reload [-n] [-p] [-d] [-f] [-c] [-T] [-i] [-C] [ directory ]
           This command was re-implemented in Shorewall 5.0.0. The pre-5.0.0 reload command is
           now called remote-restart (see below).

           Shorewall and Shorewall6
               Reload is similar to shorewall start except that it assumes that the firewall is
               already started. Existing connections are maintained. If a directory is included
               in the command, Shorewall will look in that directory first for configuration
               files.

               The -n option causes Shorewall to avoid updating the routing table(s).

               The -p option causes the connection tracking table to be flushed; the conntrack
               utility must be installed to use this option.

               The -d option causes the compiler to run under the Perl debugger.

               The -f option suppresses the compilation step and simply reused the compiled
               script which last started/restarted Shorewall, provided that /etc/shorewall and
               its contents have not been modified since the last start/restart.

               The -c option was added in Shorewall 4.4.20 and performs the compilation step
               unconditionally, overriding the AUTOMAKE setting in shorewall.conf[2](5)
               (Shorewall and Shorewall6 only). When both -f and -c are present, the result is
               determined by the option that appears last.

               The -T option was added in Shorewall 4.5.3 and causes a Perl stack trace to be
               included with each compiler-generated error and warning message.

               The -i option was added in Shorewall 4.6.0 and causes a warning message to be
               issued if the current line contains alternative input specifications following a
               semicolon (";"). Such lines will be handled incorrectly if INLINE_MATCHES is set
               to Yes in shorewall.conf[2](5) (shorewall6.conf[3](5))..

               The -C option was added in Shorewall 4.6.5 and is only meaningful when
               AUTOMAKE=Yes in shorewall.conf[2](5) (shorewall6.conf[3](5)). If an existing
               firewall script is used and if that script was the one that generated the current
               running configuration, then the running netfilter configuration will be reloaded
               as is so as to preserve the iptables packet and byte counters.

           Shorewall-lite and Shorewall6-lite
               Reload is similar to shorewall start except that it assumes that the firewall is
               already started. Existing connections are maintained.

               The -n option causes Shorewall to avoid updating the routing table(s).

               The -p option causes the connection tracking table to be flushed; the conntrack
               utility must be installed to use this option.

               The -C option was added in Shorewall 4.6.5 If the existing firewall script is the
               one that generated the current running configuration, then the running netfilter
               configuration will be reloaded as is so as to preserve the iptables packet and
               byte counters.

       remote-getcaps [-R] [-r root-user-name] [ [ -D ] directory ] [ system ]
           Added in Shoreall 5.2.0, this command executes shorewall[6]-lite show capabilities -f
           > /var/lib/shorewall[6]-lite/capabilities on the remote system via ssh then the
           generated file is copied to directory on the local system. If no directory is given,
           the current working directory is assumed.

           if -R is included, the remote shorewallrc file is also copied to directory.

           If -r is included, it specifies that the root user on system is named root-user-name
           rather than "root".

       remote-getrc [-c] [-r root-user-name] [ [ -D ] directory ] [ system ]
           Added in Shoreall 5.2.0, this command copies the shorewallrc file from the remote
           system to directory on the local system. If no directory is given, the current working
           directory is assumed.

           if -c is included, the remote capabilities are also copied to directory, as is done by
           the remote-getcaps command.

           If -r is included, it specifies that the root user on system is named root-user-name
           rather than "root".

       remote-start [-n] [-s] [-c] [-r root-user-name] [-T] [-i] [ [ -D ] directory ] [ system ]
           This command was renamed from load in Shorewall 5.0.0 and is only available in
           Shorewall and Shoreawall6.

           If directory is omitted, the current working directory is assumed. Allows a non-root
           user to compile a shorewall script and install it on a system (provided that the user
           has root access to the system via ssh). The command is equivalent to:

                   /sbin/shorewall compile -e directory directory/firewall &&\
                   scp directory/firewall directory/firewall.conf root@system:/var/lib/shorewall-lite/ &&\
                   ssh root@system '/sbin/shorewall-lite start'

           In other words, the configuration in the specified (or defaulted) directory is
           compiled to a file called firewall in that directory. If compilation succeeds, then
           firewall is copied to system using scp. If the copy succeeds, Shorewall Lite on system
           is started via ssh. Beginning with Shorewall 5.0.13, if system is omitted, then the
           FIREWALL option setting in shorewall.conf[12](5) (shorewall6.conf(5)[3]) is assumed.
           In that case, if you want to specify a directory, then the -D option must be given.

           The -n option causes Shorewall to avoid updating the routing table(s).

           If -s is specified and the start command succeeds, then the remote Shorewall-lite
           configuration is saved by executing shorewall-lite save via ssh.

           if -c is included, the command shorewall[6]-lite show capabilities -f >
           /var/lib/shorewall[6]-lite/capabilities is executed via ssh then the generated file is
           copied to directory using scp. This step is performed before the configuration is
           compiled.

           If -r is included, it specifies that the root user on system is named root-user-name
           rather than "root".

           The -T option was added in Shorewall 4.5.3 and causes a Perl stack trace to be
           included with each compiler-generated error and warning message.

       remote-reload [-s] [-c] [-r root-user-name] [-T] [-i] [ [ -D ] directory ] [ system ]
           This command was added in Shorewall 5.0.0 and is only available in Shorewall and
           Shorewall6.

           If directory is omitted, the current working directory is assumed. Allows a non-root
           user to compile a shorewall script and install it on a system (provided that the user
           has root access to the system via ssh). The command is equivalent to:

                   /sbin/shorewall compile -e directory directory/firewall &&\
                   scp directory/firewall directory/firewall.conf root@system:/var/lib/shorewall-lite/ &&\
                   ssh root@system '/sbin/shorewall-lite reload'

           In other words, the configuration in the specified (or defaulted) directory is
           compiled to a file called firewall in that directory. If compilation succeeds, then
           firewall is copied to system using scp. If the copy succeeds, Shorewall Lite on system
           is restarted via ssh. Beginning with Shorewall 5.0.13, if system is omitted, then the
           FIREWALL option setting in shorewall6.conf(5)[13] (shorewall6.conf[3](5)) is assumed.
           In that case, if you want to specify a directory, then the -D option must be given.

           If -s is specified and the restart command succeeds, then the remote Shorewall-lite
           configuration is saved by executing shorewall-lite save via ssh.

           if -c is included, the command shorewall-lite show capabilities -f >
           /var/lib/shorewall-lite/capabilities is executed via ssh then the generated file is
           copied to directory using scp. This step is performed before the configuration is
           compiled.

           If -r is included, it specifies that the root user on system is named root-user-name
           rather than "root".

           The -T option was added in Shorewall 4.5.3 and causes a Perl stack trace to be
           included with each compiler-generated error and warning message.

           The -i option was added in Shorewall 4.6.0 and causes a warning message to be issued
           if the current line contains alternative input specifications following a semicolon
           (";"). Such lines will be handled incorrectly if INLINE_MATCHES is set to Yes in
           shorewall.conf[2](5) (shorewall6.conf[3](5)).

       remote-restart [-s] [-c] [-r root-user-name] [-T] [-i] [ [ -D ] directory ] [ system ]
           This command was renamed from reload in Shorewall 5.0.0 and is available in Shorewall
           and Shorewall6 only.

           If directory is omitted, the current working directory is assumed. Allows a non-root
           user to compile a shorewall script and install it on a system (provided that the user
           has root access to the system via ssh). The command is equivalent to:

                   /sbin/shorewall compile -e directory directory/firewall &&\
                   scp directory/firewall directory/firewall.conf root@system:/var/lib/shorewall-lite/ &&\
                   ssh root@system '/sbin/shorewall-lite restart'

           In other words, the configuration in the specified (or defaulted) directory is
           compiled to a file called firewall in that directory. If compilation succeeds, then
           firewall is copied to system using scp. If the copy succeeds, Shorewall Lite on system
           is restarted via ssh. Beginning with Shorewall 5.0.13, if system is omitted, then the
           FIREWALL option setting in shorewall6.conf(5)[13] (shorewall6.conf[3](5)) is assumed.
           In that case, if you want to specify a directory, then the -D option must be given.

           If -s is specified and the restart command succeeds, then the remote Shorewall-lite
           configuration is saved by executing shorewall-lite save via ssh.

           if -c is included, the command shorewall-lite show capabilities -f >
           /var/lib/shorewall-lite/capabilities is executed via ssh then the generated file is
           copied to directory using scp. This step is performed before the configuration is
           compiled.

           If -r is included, it specifies that the root user on system is named root-user-name
           rather than "root".

           The -T option was added in Shorewall 4.5.3 and causes a Perl stack trace to be
           included with each compiler-generated error and warning message.

           The -i option was added in Shorewall 4.6.0 and causes a warning message to be issued
           if the current line contains alternative input specifications following a semicolon
           (";"). Such lines will be handled incorrectly if INLINE_MATCHES is set to Yes in
           shorewall.conf[2](5) (shorewall6.conf[3](5).

       reset [chain, ...]
           Resets the packet and byte counters in the specified chain(s). If no chain is
           specified, all the packet and byte counters in the firewall are reset.

           Beginning with Shorewall 5.0.0, chain may be composed of both a table name and a chain
           name separated by a colon (e.g., mangle:PREROUTING). Chain names following that don't
           include a table name are assumed to be in that same table. If no table name is given
           in the command, the filter table is assumed.

       restart [-n] [-p] [-d] [-f] [-c] [-T] [-i] [-C] [ directory ]
           Beginning with Shorewall 5.0.0, this command performs a true restart. The firewall is
           completely stopped as if a stop command had been issued then it is started again.

           Shorewall and Shorewall6
               If a directory is included in the command, Shorewall will look in that directory
               first for configuration files.

               The -n option causes Shorewall to avoid updating the routing table(s).

               The -p option causes the connection tracking table to be flushed; the conntrack
               utility must be installed to use this option.

               The -d option causes the compiler to run under the Perl debugger.

               The -f option suppresses the compilation step and simply reused the compiled
               script which last started/restarted Shorewall, provided that /etc/shorewall and
               its contents have not been modified since the last start/restart.

               The -c option was added in Shorewall 4.4.20 and performs the compilation step
               unconditionally, overriding the AUTOMAKE setting in shorewall.conf[2](5). When
               both -f and -c are present, the result is determined by the option that appears
               last.

               The -T option was added in Shorewall 4.5.3 and causes a Perl stack trace to be
               included with each compiler-generated error and warning message.

               The -i option was added in Shorewall 4.6.0 and causes a warning message to be
               issued if the current line contains alternative input specifications following a
               semicolon (";"). Such lines will be handled incorrectly if INLINE_MATCHES is set
               to Yes in shorewall.conf[2](5).

               The -C option was added in Shorewall 4.6.5 and is only meaningful when
               AUTOMAKE=Yes in shorewall.conf[2](5). If an existing firewall script is used and
               if that script was the one that generated the current running configuration, then
               the running netfilter configuration will be reloaded as is so as to preserve the
               iptables packet and byte counters.

           Shorewall-lite and Shorewall6-lite
               The -n option causes Shorewall to avoid updating the routing table(s).

               The -p option causes the connection tracking table to be flushed; the conntrack
               utility must be installed to use this option.

               The -C option was added in Shorewall 4.6.5 If the existing firewall script is the
               one that generated the current running configuration, then the running netfilter
               configuration will be reloaded as is so as to preserve the iptables packet and
               byte counters.

       restore  [-n] [-p] [-C] [ filename ]
           Restore Shorewall to a state saved using the shorewall save command. Existing
           connections are maintained. The filename names a restore file in /var/lib/shorewall
           created using shorewall save; if no filename is given then Shorewall will be restored
           from the file specified by the RESTOREFILE option in shorewall.conf[2](5)
           (shorewall6.conf[3](5)).

               Caution
               If your iptables ruleset depends on variables that are detected at run-time,
               either in your params file or by Shorewall-generated code, restore will use the
               values that were current when the ruleset was saved, which may be different from
               the current values.
           The -n option causes Shorewall to avoid updating the routing table(s).

           The -p option, added in Shorewall 4.6.5, causes the connection tracking table to be
           flushed; the conntrack utility must be installed to use this option.

           The -C option was added in Shorewall 4.6.5. If the -C option was specified during
           shorewall save, then the counters saved by that operation will be restored.

       run command [ parameter ... ]
           Added in Shorewall 4.6.3. Executes command in the context of the generated script
           passing the supplied parameters. Normally, the command will be a function declared in
           lib.private.

           Before executing the command, the script will detect the configuration, setting all
           SW_* variables and will run your init extension script with $COMMAND = 'run'.

           If there are files in the CONFIG_PATH that were modified after the current firewall
           script was generated, the following warning message is issued:
               WARNING: /var/lib/shorewall/firewall is not up to
                           date

       safe-reload [-d] [-p] [-t timeout ] [ directory ]
           Added in Shorewall 5.0.0, this command performs the same function as did safe_restart
           in earlier releases. The command is available in Shorewall and Shorewall6 only.

           Only allowed if Shorewall is running. The current configuration is saved in
           /var/lib/shorewall/safe-reload (see the save command below) then a shorewall reload is
           done. You will then be prompted asking if you want to accept the new configuration or
           not. If you answer "n" or if you fail to answer within 60 seconds (such as when your
           new configuration has disabled communication with your terminal), the configuration is
           restored from the saved configuration. If a directory is given, then Shorewall will
           look in that directory first when opening configuration files.

           Beginning with Shorewall 4.5.0, you may specify a different timeout value using the -t
           option. The numeric timeout may optionally be followed by an s, m or h suffix (e.g.,
           5m) to specify seconds, minutes or hours respectively. If the suffix is omitted,
           seconds is assumed.

       safe-restart [-d] [-p] [-t timeout ] [ directory ]
           Only allowed if Shorewall[6] is running and is not available in Shorewall-lite and
           Shorewall6-lite. The current configuration is saved in /var/lib/shorewall/safe-restart
           (see the save command below) then a shorewall restart is done. You will then be
           prompted asking if you want to accept the new configuration or not. If you answer "n"
           or if you fail to answer within 60 seconds (such as when your new configuration has
           disabled communication with your terminal), the configuration is restored from the
           saved configuration. If a directory is given, then Shorewall will look in that
           directory first when opening configuration files.

           Beginning with Shorewall 4.5.0, you may specify a different timeout value using the -t
           option. The numeric timeout may optionally be followed by an s, m or h suffix (e.g.,
           5m) to specify seconds, minutes or hours respectively. If the suffix is omitted,
           seconds is assumed.

       safe-start [-d] [-p] [-ttimeout ] [ directory ]
           Shorewall is started normally. You will then be prompted asking if everything went all
           right. If you answer "n" or if you fail to answer within 60 seconds (such as when your
           new configuration has disabled communication with your terminal), a shorewall clear is
           performed for you. If a directory is given, then Shorewall will look in that directory
           first when opening configuration files.

           Beginning with Shorewall 4.5.0, you may specify a different timeout value using the -t
           option. The numeric timeout may optionally be followed by an s, m or h suffix (e.g.,
           5m) to specify seconds, minutes or hours respectively. If the suffix is omitted,
           seconds is assumed.

           This command is available in Shorewall and Shorewall6 only.

       save  [-C] [ filename ]
           Creates a snapshot of the currently running firewall. The dynamic blacklist is stored
           in /var/lib/shorewall/save. The state of the firewall is stored in
           /var/lib/shorewall/filename for use by the shorewall restore command. If filename is
           not given then the state is saved in the file specified by the RESTOREFILE option in
           shorewall.conf[2](5) (shorewall6.conf[3](5)).

           The -C option, added in Shorewall 4.6.5, causes the iptables packet and byte counters
           to be saved along with the chains and rules.

       savesets
           Added in shorewall 4.6.8. Performs the same action as the stop command with respect to
           saving ipsets (see the SAVE_IPSETS option in shorewall.conf[2] (5)
           (shorewall6.conf[3](5)). This command may be used to proactively save your ipset
           contents in the event that a system failure occurs prior to issuing a stop command.

       show
           The show command can have a number of different arguments:

           action action
               Lists the named action file. Available on Shorewall and Shorewall6 only.

           actions
               Produces a report about the available actions (built-in, standard and
               user-defined). Available on Shorewall and Shorewall6 only.

           bl|blacklists [-x]
               Added in Shorewall 4.6.2. Displays the dynamic chain along with any chains
               produced by entries in shorewall-blrules(5). The -x option is passed directly
               through to iptables and causes actual packet and byte counts to be displayed.
               Without this option, those counts are abbreviated.

           [-f] capabilities
               Displays your kernel/iptables capabilities. The -f option causes the display to be
               formatted as a capabilities file for use with compile -e.

           [-b] [-x] [-l] [-t {filter|mangle|nat|raw}] [ chain... ]
               The rules in each chain are displayed using the iptables -L chain -n -v command.
               If no chain is given, all of the chains in the filter table are displayed. The -x
               option is passed directly through to iptables and causes actual packet and byte
               counts to be displayed. Without this option, those counts are abbreviated. The -t
               option specifies the Netfilter table to display. The default is filter.

               The -b ('brief') option causes rules which have not been used (i.e. which have
               zero packet and byte counts) to be omitted from the output. Chains with no rules
               displayed are also omitted from the output.

               The -l option causes the rule number for each Netfilter rule to be displayed.

               If the -t option and the chain keyword are both omitted and any of the listed
               chains do not exist, a usage message is displayed.

           classifiers|filters
               Displays information about the packet classifiers defined on the system as a
               result of traffic shaping configuration.

           config
               Displays distribution-specific defaults.

           connections [filter_parameter ...]
               Displays the IP connections currently being tracked by the firewall.

               If the conntrack utility is installed, beginning with Shorewall 4.6.11 the set of
               connections displayed can be limited by including conntrack filter parameters (-p
               , -s, --dport, etc). See conntrack(8) for details.

           event event
               Added in Shorewall 4.5.19. Displays the named event.

           events
               Added in Shorewall 4.5.19. Displays all events.

           ip
               Displays the system's IPv4 configuration.

           ipa
               Added in Shorewall 4.4.17. Displays the per-IP accounting counters
               (shorewall-accounting[14] (5), shorewall6-accounting[15](5)).

           ipsec
               Added in Shorewall 5.1.0. Displays the contents of the IPSEC Security Policy
               Database (SPD) and Security Association Database (SAD). SAD keys are not
               displayed.

           [-m] log
               Displays the last 20 Shorewall messages from the log file specified by the LOGFILE
               option in shorewall.conf[2](5) (shorewall6.conf[3](5)). The -m option causes the
               MAC address of each packet source to be displayed if that information is
               available.

           macros
               Displays information about each macro defined on the firewall system (Shorewall
               and Shorewall6 only)

           macro macro
               Added in Shorewall 4.4.6. Displays the file that implements the specified macro
               (usually /usr/share/shorewall/macro.macro). Available only in Shorewall and
               Shorewall6.

           [-x] mangle
               Displays the Netfilter mangle table using the command iptables -t mangle -L -n -v.
               The -x option is passed directly through to iptables and causes actual packet and
               byte counts to be displayed. Without this option, those counts are abbreviated.

           marks
               Added in Shorewall 4.4.26. Displays the various fields in packet marks giving the
               min and max value (in both decimal and hex) and the applicable mask (in hex).

           [-x] nat
               Displays the Netfilter nat table using the command iptables -t nat -L -n -v. The
               -x option is passed directly through to iptables and causes actual packet and byte
               counts to be displayed. Without this option, those counts are abbreviated.

           opens
               Added in Shorewall 4.5.8. Displays the iptables rules in the 'dynamic' chain
               created through use of the open command..

           policies
               Added in Shorewall 4.4.4. Displays the applicable policy between each pair of
               zones. Note that implicit intrazone ACCEPT policies are not displayed for zones
               associated with a single network where that network doesn't specify routeback.

           rc
               Added in Shorewall 5.2.0. Displays the contents of
               $SHAREDIR/shorewall/shorewallrc.

           [-c] routing
               Displays the system's IPv4 routing configuration. The -c option causes the route
               cache to be displayed along with the other routing information.

           [-x] raw
               Displays the Netfilter raw table using the command iptables -t raw -L -n -v. The
               -x option is passed directly through to iptables and causes actual packet and byte
               counts to be displayed. Without this option, those counts are abbreviated.

           saves
               Added in Shorewall 5.2.0. Lists snapshots created by the save command. Each
               snapshot is listed with the date and time when it was taken. If there is a
               snapshot with the name specified in the RESTOREFILE option in
               shorewall.conf(5[12]), that snapshot is listed as the default snapshot for the
               restore command.

           tc
               Displays information about queuing disciplines, classes and filters.

           zones
               Displays the current composition of the Shorewall zones on the system.

       start  [-n] [-p] [-d] [-f] [-c] [-T] [-i] [-C] [ directory ]

           Shorewall and Shorewall6
               Start shorewall[6]. Existing connections through shorewall managed interfaces are
               untouched. New connections will be allowed only if they are allowed by the
               firewall rules or policies. If a directory is included in the command, Shorewall
               will look in that directory first for configuration files. If -f is specified, the
               saved configuration specified by the RESTOREFILE option in shorewall.conf[2](5)
               (shorewall6.conf[3](5)) will be restored if that saved configuration exists and
               has been modified more recently than the files in /etc/shorewall. When -f is
               given, a directory may not be specified.

               Update: In Shorewall 4.4.20, a new LEGACY_FASTSTART option was added to
               shorewall.conf[2](5) (shorewall6.conf[3](5)). When LEGACY_FASTSTART=No, the
               modification times of files in /etc/shorewall are compared with that of
               /var/lib/shorewall/firewall (the compiled script that last started/restarted the
               firewall).

               The -n option causes Shorewall to avoid updating the routing table(s).

               The -p option causes the connection tracking table to be flushed; the conntrack
               utility must be installed to use this option.

               The -c option was added in Shorewall 4.4.20 and performs the compilation step
               unconditionally, overriding the AUTOMAKE setting in shorewall.conf[2](5)
               (shorewall6.conf[3](5)). When both -f and -care present, the result is determined
               by the option that appears last.

               The -T option was added in Shorewall 4.5.3 and causes a Perl stack trace to be
               included with each compiler-generated error and warning message.

               The -i option was added in Shorewall 4.6.0 and causes a warning message to be
               issued if the current line contains alternative input specifications following a
               semicolon (";"). Such lines will be handled incorrectly if INLINE_MATCHES is set
               to Yes in shorewall.conf(5)[2] (shorewall6.conf[3](5)).

               The -C option was added in Shorewall 4.6.5 and is only meaningful when the -f
               option is also specified. If the previously-saved configuration is restored, and
               if the -C option was also specified in the save command, then the packet and byte
               counters will be restored.

           Shorewall-lite and Shorewall6-lite
               Start Shorewall[6] Lite. Existing connections through shorewall[6]-lite managed
               interfaces are untouched. New connections will be allowed only if they are allowed
               by the firewall rules or policies.

               The -p option causes the connection tracking table to be flushed; the conntrack
               utility must be installed to use this option.

               The -n option prevents the firewall script from modifying the current routing
               configuration.

               The -f option was added in Shorewall 4.6.5. If the RESTOREFILE named in
               shorewall.conf[12](5) exists, is executable and is not older than the current
               filewall script, then that saved configuration is restored.

               The -C option was added in Shorewall 4.6.5 and is only meaningful when the -f
               option is also specified. If the previously-saved configuration is restored, and
               if the -C option was also specified in the save command, then the packet and byte
               counters will be restored.

       stop [-f]
           Stops the firewall. All existing connections, except those listed in
           shorewall-routestopped[16](5) or permitted by the ADMINISABSENTMINDED option in
           shorewall.conf[2](5), are taken down. The only new traffic permitted through the
           firewall is from systems listed in shorewall-routestopped[16](5) or by
           ADMINISABSENTMINDED.

           If -f is given, the command will be processed by the compiled script that executed the
           last successful start, restart or reload command if that script exists.

       status [-i]
           Produces a short report about the state of the Shorewall-configured firewall.

           The -i option was added in Shorewall 4.6.2 and causes the status of each optional or
           provider interface to be displayed.

       try directory [ timeout ]
           This command is available in Shorewall and Shorewall6 only.

           If Shorewall[6] is started then the firewall state is saved to a temporary saved
           configuration (/var/lib/shorewall/.try). Next, if Shorewall[6] is currently started
           then a restart command is issued using the specified configuration directory;
           otherwise, a start command is performed using the specified configuration directory.
           if an error occurs during the compilation phase of the restart or start, the command
           terminates without changing the Shorewall[6] state. If an error occurs during the
           restart phase, then a shorewall restore is performed using the saved configuration. If
           an error occurs during the start phase, then Shorewall is cleared. If the
           start/restart succeeds and a timeout is specified then a clear or restore is performed
           after timeout seconds.

           Beginning with Shorewall 4.5.0, the numeric timeout may optionally be followed by an
           s, m or h suffix (e.g., 5m) to specify seconds, minutes or hours respectively. If the
           suffix is omitted, seconds is assumed.

       update  [-d] [-r] [-T] [-a] [-i] [-A] [ directory ]
           This command is available only in Shorewall and Shorewall6.

           Added in Shorewall 4.4.21 and causes the compiler to update
           /etc/shorewall/shorewall.conf then validate the configuration. The update will add
           options not present in the old file with their default values, and will move
           deprecated options with non-defaults to a deprecated options section at the bottom of
           the file. Your existing shorewall.conf file is renamed shorewall.conf.bak.

           The command was extended over the years with a set of options that caused additional
           configuration updates.

           ·   Convert an existing blacklist file into an equivalent blrules file.

           ·   Convert an existing routestopped file into an equivalent stoppedrules file.

           ·   Convert existing tcrules and tos files into an equivalent mangle file.

           ·   Convert an existing notrack file into an equivalent conntrack file.

           ·   Convert FORMAT, SECTION and COMMENT entries into ?FORMAT, ?SECTION and ?COMMENT
               directives.

           In each case, the old file is renamed with a .bak suffix.

           In Shorewall 5.0.0, the options were eliminated and the update command performs all of
           the updates described above.

               Important
               There are some notable restrictions with the update command:

                1. Converted rules will be appended to the existing file; if there is no existing
                   file in the CONFIG_PATH, one will be created in the directory specified in the
                   command or in the first entry in the CONFIG_PATH (normally /etc/shorewall)
                   otherwise.

                2. Existing comments in the file being converted will not be transferred to the
                   output file.

                3. With the exception of the notrack->conntrack conversion, INCLUDEd files will
                   be expanded inline in the output file.

                4. Columns in the output file will be separated by a single tab character; there
                   is no attempt made to otherwise align the columns.

                5. Prior to Shorewall 5.0.15, shell variables will be expanded in the output
                   file.

                6. Prior to Shorewall 5.0.15, lines omitted by compiler directives (?if ....,
                   etc.) will not appear in the output file.

                       Important
                       Because the translation of the 'blacklist' and 'routestopped' files is not
                       1:1, omitted lines and compiler directives are not transferred to the
                       converted files. If either are present, the compiler issues a warning:

                            WARNING: "Omitted rules and compiler directives were not translated
           The -a option causes the updated shorewall.conf file to be annotated with
           documentation.

           The -i option was added in Shorewall 4.6.0 and causes a warning message to be issued
           if the current line contains alternative input specifications following a semicolon
           (";"). Such lines will be handled incorrectly if INLINE_MATCHES is set to Yes in
           shorewall.conf[2](5).

           The -A option is included for compatibility with Shorewall 4.6 and is equivalent to
           specifying the -i option.

           For a description of the other options, see the check command above.

       version [-a]
           Displays Shorewall's version. The -a option is included for compatibility with earlier
           Shorewall releases and is ignored.

EXIT STATUS

       In general, when a command succeeds, status 0 is returned; when the command fails, a
       non-zero status is returned.

       The status command returns exit status as follows:

       0 - Firewall is started.

       3 - Firewall is stopped or cleared

       4 - Unknown state; usually means that the firewall has never been started.

ENVIRONMENT

       Two environmental variables are recognized by Shorewall:

       SHOREWALL_INIT_SCRIPT
           When set to 1, causes Std out to be redirected to the file specified in the
