NAME
firewall-cmd - firewalld command line client
SYNOPSIS
firewall-cmd [OPTIONS...]
DESCRIPTION
firewall-cmd is the command line client of the firewalld daemon. It provides interface to manage runtime
and permanent configuration.
The runtime configuration in firewalld is separated from the permanent configuration. This means that
things can get changed in the runtime or permanent configuration.
OPTIONS
The following options are supported:
General Options
-h, --help
Prints a short help text and exists.
-V, --version
Print the version string of firewalld. This option is not combinable with other options.
-q, --quiet
Do not print status messages.
Status Options
--state
Check whether the firewalld daemon is active (i.e. running). Returns an exit code 0 if it is active,
NOT_RUNNING otherwise (see the section called “EXIT CODES”). This will also print the state to
STDOUT.
--reload
Reload firewall rules and keep state information. Current permanent configuration will become new
runtime configuration, i.e. all runtime only changes done until reload are lost with reload if they
have not been also in permanent configuration.
--complete-reload
Reload firewall completely, even netfilter kernel modules. This will most likely terminate active
connections, because state information is lost. This option should only be used in case of severe
firewall problems. For example if there are state information problems that no connection can be
established with correct firewall rules.
Permanent Options
--permanent
The permanent option --permanent can be used to set options permanently. These changes are not
effective immediately, only after service restart/reload or system reboot. Without the --permanent
option, a change will only be part of the runtime configuration. The --permanent option can not be
used with all options.
If you want to make a change in runtime and permanent configuration, use the same call with and
without the--permanent option.
The --permanent option can be optionally added to all options further down where it is supported.
Zone Options
--get-default-zone
Print default zone for connections and interfaces.
--set-default-zone=zone
Set default zone for connections and interfaces where no zone has been selected. Setting the default
zone changes the zone for the connections or interfaces, that are using the default zone.
This is a runtime and permanent change.
--get-active-zones
Print currently active zones altogether with interfaces and sources used in these zones. Active zones
are zones, that have a binding to an interface or source. The output format is:
zone1
interfaces: interface1 interface2 ..
sources: source1 ..
zone2
interfaces: interface3 ..
zone3
sources: source2 ..
If there are no interfaces or sources bound to the zone, the corresponding line will be omitted.
[--permanent] --get-zones
Print predefined zones as a space separated list.
[--permanent] --get-services
Print predefined services as a space separated list.
[--permanent] --get-icmptypes
Print predefined icmptypes as a space separated list.
[--permanent] --get-zone-of-interface=interface
Print the name of the zone the interface is bound to or no zone.
[--permanent] --get-zone-of-source=source[/mask]
Print the name of the zone the source[/mask] is bound to or no zone.
[--permanent] --list-all-zones
List everything added for or enabled in all zones. The output format is:
zone1
interfaces: interface1 ..
sources: source1 ..
services: service1 ..
ports: port1 ..
forward-ports:
forward-port1
..
icmp-blocks: icmp-type1 ..
rich rules:
rich-rule1
..
..
Options to Adapt and Query Zones

Options to Handle Bindings of Interfaces
Binding an interface to a zone means that this zone settings are used to restrict traffic via the
interface.
Options in this section affect only one particular zone. If used with --zone=zone option, they affect the
zone zone. If the option is omitted, they affect default zone (see --get-default-zone).
For a list of predefined zones use firewall-cmd --get-zones.
An interface name is a string up to 16 characters long, that may not contain ' ', '/', '!' and '*'.
[--permanent] [--zone=zone] --list-interfaces
List interfaces that are bound to zone zone as a space separated list. If zone is omitted, default
zone will be used.
[--permanent] [--zone=zone] --add-interface=interface
Bind interface interface to zone zone. If zone is omitted, default zone will be used.
[--zone=zone] --change-interface=interface
Change zone the interface interface is bound to to zone zone. If zone is omitted, default zone will
be used. If old and new zone are the same, the call will be ignored without an error. If the
interface has not been bound to a zone before, it will behave like --add-interface.
[--permanent] [--zone=zone] --query-interface=interface
Query whether interface interface is bound to zone zone. Returns 0 if true, 1 otherwise.
[--permanent] [--zone=zone] --remove-interface=interface
Remove binding of interface interface from zone zone. If zone is omitted, default zone will be used.
Options to Handle Bindings of Sources
Binding a source to a zone means that this zone settings will be used to restrict traffic from this
source.
A source address or address range is either an IP address or a network IP address with a mask for IPv4 or
IPv6. For IPv4, the mask can be a network mask or a plain number. For IPv6 the mask is a plain number.
The use of host names is not supported.
Options in this section affect only one particular zone. If used with --zone=zone option, they affect the
zone zone. If the option is omitted, they affect default zone (see --get-default-zone).
For a list of predefined zones use firewall-cmd [--permanent] --get-zones.
[--permanent] [--zone=zone] --list-sources
List sources that are bound to zone zone as a space separated list. If zone is omitted, default zone
will be used.
[--permanent] [--zone=zone] --add-source=source[/mask]
Bind source source[/mask] to zone zone. If zone is omitted, default zone will be used.
[--zone=zone] --change-source=source[/mask]
Change zone the source source[/mask] is bound to to zone zone. If zone is omitted, default zone will
be used. If old and new zone are the same, the call will be ignored without an error. If the source
has not been bound to a zone before, it will behave like --add-source.
[--permanent] [--zone=zone] --query-source=source[/mask]
Query whether the source source[/mask] is bound to the zone zone. Returns 0 if true, 1 otherwise.
[--permanent] [--zone=zone] --remove-source=source[/mask]
Remove binding of source source[/mask] from zone zone. If zone is omitted, default zone will be used.
Direct Options
The direct options give a more direct access to the firewall. These options require user to know basic
iptables concepts, i.e. table (filter/mangle/nat/...), chain (INPUT/OUTPUT/FORWARD/...), commands
(-A/-D/-I/...), parameters (-p/-s/-d/-j/...) and targets (ACCEPT/DROP/REJECT/...).
Direct options should be used only as a last resort when it's not possible to use for example
--add-service=service or --add-rich-rule='rule'.
The first argument of each option has to be ipv4 or ipv6 or eb. With ipv4 it will be for IPv4
(iptables(8)), with ipv6 for IPv6 (ip6tables(8)) and with eb for ethernet bridges (ebtables(8)).
[--permanent] --direct --get-all-chains
Get all chains added to all tables.
This option concerns only chains previously added with --direct --add-chain.
[--permanent] --direct --get-chains { ipv4 | ipv6 | eb } table
Get all chains added to table table as a space separated list.
This option concerns only chains previously added with --direct --add-chain.
[--permanent] --direct --add-chain { ipv4 | ipv6 | eb } table chain
Add a new chain with name chain to table table.
There already exist basic chains to use with direct options, for example INPUT_direct chain (see
iptables-save | grep direct output for all of them). These chains are jumped into before chains for
zones, i.e. every rule put into INPUT_direct will be checked before rules in zones.
[--permanent] --direct --remove-chain { ipv4 | ipv6 | eb } table chain
Remove the chain with name chain from table table.
[--permanent] --direct --query-chain { ipv4 | ipv6 | eb } table chain
Return whether a chain with name chain exists in table table. Returns 0 if true, 1 otherwise.
This option concerns only chains previously added with --direct --add-chain.
[--permanent] --direct --get-all-rules
Get all rules added to all chains in all tables as a newline separated list of the priority and
arguments.
[--permanent] --direct --get-rules { ipv4 | ipv6 | eb } table chain
Get all rules added to chain chain in table table as a newline separated list of the priority and
arguments.
[--permanent] --direct --add-rule { ipv4 | ipv6 | eb } table chain priority args
Add a rule with the arguments args to chain chain in table table with priority priority.
The priority is used to order rules. Priority 0 means add rule on top of the chain, with a higher
priority the rule will be added further down. Rules with the same priority are on the same level and
the order of these rules is not fixed and may change. If you want to make sure that a rule will be
added after another one, use a low priority for the first and a higher for the following.
[--permanent] --direct --remove-rule { ipv4 | ipv6 | eb } table chain priority args
Remove a rule with priority and the arguments args from chain chain in table table.
[--permanent] --direct --query-rule { ipv4 | ipv6 | eb } table chain priority args
Return whether a rule with priority and the arguments args exists in chain chain in table table.
Returns 0 if true, 1 otherwise.
--direct --passthrough { ipv4 | ipv6 | eb } args
Pass a command through to the firewall. args can be all iptables, ip6tables and ebtables command
line arguments.
--permanent --direct --get-all-passthroughs
Get all permanent passthrough as a newline separated list of the ipv value and arguments.
--permanent --direct --get-passthroughs { ipv4 | ipv6 | eb }
Get all permanent passthrough rules for the ipv value as a newline separated list of the priority and
arguments.
--permanent --direct --add-passthrough { ipv4 | ipv6 | eb } args
Add a permanent passthrough rule with the arguments args for the ipv value.
--permanent --direct --remove-passthrough { ipv4 | ipv6 | eb } args
Remove a permanent passthrough rule with the arguments args for the ipv value.
--permanent --direct --query-passthrough { ipv4 | ipv6 | eb } args
Return whether a permanent passthrough rule with the arguments args exists for the ipv value. Returns
0 if true, 1 otherwise.
Lockdown Options
Local applications or services are able to change the firewall configuration if they are running as root
(example: libvirt) or are authenticated using PolicyKit. With this feature administrators can lock the
firewall configuration so that only applications on lockdown whitelist are able to request firewall
changes.
The lockdown access check limits D-Bus methods that are changing firewall rules. Query, list and get
methods are not limited.
The lockdown feature is a very light version of user and application policies for firewalld and is turned
off by default.
--lockdown-on
Enable lockdown. Be careful - if firewall-cmd is not on lockdown whitelist when you enable lockdown
you won't be able to disable it again with firewall-cmd, you would need to edit firewalld.conf.
This is a runtime and permanent change.
--lockdown-off
Disable lockdown.
This is a runtime and permanent change.
--query-lockdown
Query whether lockdown is enabled. Returns 0 if lockdown is enabled, 1 otherwise.
Lockdown Whitelist Options
The lockdown whitelist can contain commands, contexts, users and user ids.
If a command entry on the whitelist ends with an asterisk '*', then all command lines starting with the
command will match. If the '*' is not there the absolute command inclusive arguments must match.
Commands for user root and others is not always the same. Example: As root /bin/firewall-cmd is used, as
a normal user /usr/bin/firewall-cmd is be used on Fedora.
The context is the security (SELinux) context of a running application or service. To get the context of
a running application use ps -e --context.
Warning: If the context is unconfined, then this will open access for more than the desired application.
The lockdown whitelist entries are checked in the following order:
1. context
2. uid
3. user
4. command
[--permanent] --list-lockdown-whitelist-commands
List all command lines that are on the whitelist.
[--permanent] --add-lockdown-whitelist-command=command
Add the command to the whitelist.
[--permanent] --remove-lockdown-whitelist-command=command
Remove the command from the whitelist.
[--permanent] --query-lockdown-whitelist-command=command
Query whether the command is on the whitelist. Returns 0 if true, 1 otherwise.
[--permanent] --list-lockdown-whitelist-contexts
List all contexts that are on the whitelist.
[--permanent] --add-lockdown-whitelist-context=context
Add the context context to the whitelist.
[--permanent] --remove-lockdown-whitelist-context=context
Remove the context from the whitelist.
[--permanent] --query-lockdown-whitelist-context=context
Query whether the context is on the whitelist. Returns 0 if true, 1 otherwise.
[--permanent] --list-lockdown-whitelist-uids
List all user ids that are on the whitelist.
[--permanent] --add-lockdown-whitelist-uid=uid
Add the user id uid to the whitelist.
[--permanent] --remove-lockdown-whitelist-uid=uid
Remove the user id uid from the whitelist.
[--permanent] --query-lockdown-whitelist-uid=uid
Query whether the user id uid is on the whitelist. Returns 0 if true, 1 otherwise.
[--permanent] --list-lockdown-whitelist-users
List all user names that are on the whitelist.
[--permanent] --add-lockdown-whitelist-user=user
Add the user name user to the whitelist.
[--permanent] --remove-lockdown-whitelist-user=user
Remove the user name user from the whitelist.
[--permanent] --query-lockdown-whitelist-user=user
Query whether the user name user is on the whitelist. Returns 0 if true, 1 otherwise.
Panic Options
--panic-on
Enable panic mode. All incoming and outgoing packets are dropped, active connections will expire.
Enable this only if there are serious problems with your network environment. For example if the
machine is getting hacked in.
This is a runtime only change.
--panic-off
Disable panic mode. After disabling panic mode established connections might work again, if panic
mode was enabled for a short period of time.
This is a runtime only change.
--query-panic
Returns 0 if panic mode is enabled, 1 otherwise.
EXAMPLES
For more examples see http://fedoraproject.org/wiki/FirewallD Example 1 Enable http service in default zone. This is runtime only change, i.e. effective until restart. firewall-cmd --add-service=http Example 2 Enable port 443/tcp immediately and permanently in default zone. To make the change effective immediately and also after restart we need two commands. The first command makes the change in runtime configuration, i.e. makes it effective immediately, until restart. The second command makes the change in permanent configuration, i.e. makes it effective after restart. firewall-cmd --add-port=443/tcp firewall-cmd --permanent --add-port=443/tcp
