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 an interface
to manage the runtime and permanent configurations.
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
Sequence options are the options that can be specified multiple times, the exit code is 0
if there is at least one item that succeeded. The ALREADY_ENABLED (11), NOT_ENABLED (12)
and also ZONE_ALREADY_SET (16) errors are treated as succeeded. If there are issues while
parsing the items, then these are treated as warnings and will not change the result as
long as there is a succeeded one. Without any succeeded item, the exit code will depend on
the error codes. If there is exactly one error code, then this is used. If there are more
than one then UNKNOWN_ERROR (254) will be used.
The following options are supported:
General Options
-h, --help
Prints a short help text and exits.
-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, RUNNING_BUT_FAILED if failure occurred on startup, 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.
Note: If FlushAllOnReload=no, runtime changes applied via the direct interface are not
affected and will therefore stay in place until firewalld daemon is restarted
completely. For FlushAllOnReload, see firewalld.conf(5).
--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.
Note: If FlushAllOnReload=no, runtime changes applied via the direct interface are not
affected and will therefore stay in place until firewalld daemon is restarted
completely. For FlushAllOnReload, see firewalld.conf(5).
--runtime-to-permanent
Save active runtime configuration and overwrite permanent configuration with it. The
way this is supposed to work is that when configuring firewalld you do runtime changes
only and once you're happy with the configuration and you tested that it works the way
you want, you save the configuration to disk.
--check-config
Run checks on the permanent configuration. This includes XML validity and semantics.
--reset-to-defaults
Reset configuration to firewalld's default configuration.
Log Denied Options
--get-log-denied
Print the log denied setting.
--set-log-denied=value
Add logging rules right before reject and drop rules in the INPUT, FORWARD and OUTPUT
chains for the default rules and also final reject and drop rules in zones for the
configured link-layer packet type. The possible values are: all, unicast, broadcast,
multicast and off. The default setting is off, which disables the logging.
This is a runtime and permanent change and will also reload the firewall to be able to
add the logging 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.
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.

Print the name of the zone the interface is bound to or no zone.
[--permanent] --get-zone-of-source=source[/mask]|MAC|ipset:ipset
Print the name of the zone the source is bound to or no zone.
[--permanent] --info-zone=zone
Print information about the zone zone. The output format is:
zone
interfaces: interface1 ..
sources: source1 ..
services: service1 ..
ports: port1 ..
protocols: protocol1 ..

..
source-ports: source-port1 ..
icmp-blocks: icmp-type1 ..

zone1
interfaces: interface1 ..
sources: source1 ..
services: service1 ..
ports: port1 ..
protocols: protocol1 ..
forward-ports:
forward-port1
..
icmp-blocks: icmp-type1 ..
rich rules:
rich-rule1
..

firewalld. Does not apply to user defined policies.
Options to Adapt and Query Zones and Policies
Options in this section affect only one particular zone or policy. If used with
--zone=zone or --policy=policy option, they affect the specified zone or policy. If both
options are omitted, they affect the default zone (see --get-default-zone).
[--permanent] [--zone=zone] [--policy=policy] --list-all
List everything added or enabled.
--permanent [--zone=zone] [--policy=policy] --get-target
Get the target.
--permanent [--zone=zone] [--policy=policy] --set-target=target
Set the target.
For zones target is one of: default, ACCEPT, DROP, REJECT
For policies target is one of: CONTINUE, ACCEPT, DROP, REJECT
default is similar to REJECT, but it implicitly allows ICMP packets.
--permanent [--zone=zone] [--policy=policy] --set-description=description
Set description.
--permanent [--zone=zone] [--policy=policy] --get-description

List services added as a space separated list.
[--permanent] [--zone=zone] [--permanent] [--policy=policy] --add-service=service
[--timeout=timeval]
Add a service. This option can be specified multiple times. If a timeout is supplied,
the rule will be active for the specified amount of time and will be removed
automatically afterwards. timeval is either a number (of seconds) or number followed
by one of characters s (seconds), m (minutes), h (hours), for example 20m or 1h.
The service is one of the firewalld provided services. To get a list of the supported
services, use firewall-cmd --get-services.
The --timeout option is not combinable with the --permanent option.
Note: Some services define connection tracking helpers. Helpers that may operate in
client mode (e.g. tftp) must be added to an outbound policy instead of a zone to take
effect for clients. Otherwise the helper will not be applied to the outbound traffic.
The related traffic, as defined by the connection tracking helper, on the return path
(ingress) will be allowed by the stateful firewall rules.
An example of an outbound policy for connection tracking helpers:
# firewall-cmd --permanent --new-policy clientConntrack
# firewall-cmd --permanent --policy clientConntrack --add-ingress-zone HOST
# firewall-cmd --permanent --policy clientConntrack --add-egress-zone ANY
# firewall-cmd --permanent --policy clientConntrack --add-service tftp

For IPv6 masquerading, please use the rich language.
Note: IP forwarding will be implicitly enabled.
Note (Linux < 5.5): For the iptables backend, a policy may not enable masquerade if an
ingress zone has assigned interfaces. This restriction does not exist for the nftables
backend, but does require Linux v5.5+ to function properly; otherwise it will silently
fail.

otherwise.
For the rich language rule syntax, please have a look at firewalld.richlanguage(5).
Options to Adapt and Query Zones
Options in this section affect only one particular zone. If used with --zone=zone option,
they affect the specified zone. If the option is omitted, they affect default zone (see
--get-default-zone).
[--permanent] [--zone=zone] --add-icmp-block-inversion
Enable ICMP block inversion.
[--permanent] [--zone=zone] --remove-icmp-block-inversion

Set the zone's ingress priority for packet classification.
--permanent [--zone=zone] --get-egress-priority
Get the egress priority of the zone.
--permanent [--zone=zone] --set-egress-priority

Options to Adapt and Query Policies
Options in this section affect only one particular policy. It's required to specify
--policy=policy with these options.
--permanent --policy=policy --get-priority
Get the priority.
--permanent --policy=policy --set-priority=priority
Set the priority. The priority determines the relative ordering of policies. This is
an integer value between -32768 and 32767 where -1 is the default value for new
policies and 0 is reserved for internal use.
If a priority is < 0, then the policy's rules will execute before all rules in all
zones.
If a priority is > 0, then the policy's rules will execute after all rules in all
zones.
[--permanent] --policy=policy --list-ingress-zones
List ingress zones added as a space separated list.
[--permanent] --policy=policy --add-ingress-zone=zone
Add an ingress zone. This option can be specified multiple times.
The ingress zone is one of the firewalld provided zones or one of the pseudo-zones:
HOST, ANY.
HOST is used for traffic originating from the host machine, i.e. the host running
firewalld.
ANY is used for traffic originating from any zone. This can be thought of as a wild
card for zones. However it does not include traffic originating from the host machine
- use HOST for that.
[--permanent] --policy=policy --remove-ingress-zone=zone
Remove an ingress zone. This option can be specified multiple times.
[--permanent] --policy=policy --query-ingress-zone=zone
Return whether zone has been added. Returns 0 if true, 1 otherwise.
[--permanent] --policy=policy --list-egress-zones
List egress zones added as a space separated list.
[--permanent] --policy=policy --add-egress-zone=zone
Add an egress zone. This option can be specified multiple times.
The egress zone is one of the firewalld provided zones or one of the pseudo-zones:
HOST, ANY.
For clarification on HOST and ANY see option --add-ingress-zone.
[--permanent] --policy=policy --remove-egress-zone=zone
Remove an egress zone. This option can be specified multiple times.
[--permanent] --policy=policy --query-egress-zone=zone
Return whether zone has been added. Returns 0 if true, 1 otherwise.
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.
If the interface is under control of NetworkManager, it is at first connected to
change the zone for the connection that is using the interface. If this fails, the
zone binding is created in firewalld and the limitations below apply. For interfaces
that are not under control of NetworkManager, firewalld tries to change the ZONE
setting in the ifcfg file, if the file exists.
As a end user you don't need this in most cases, because NetworkManager (or legacy
network service) adds interfaces into zones automatically (according to ZONE= option
from ifcfg-interface file) if NM_CONTROLLED=no is not set. You should do it only if
there's no /etc/sysconfig/network-scripts/ifcfg-interface file. If there is such file
and you add interface to zone with this --add-interface option, make sure the zone is
the same in both cases, otherwise the behaviour would be undefined. Please also have a
look at the firewalld(1) man page in the Concepts section. For permanent association
of interface with a zone, see also 'How to set or change a zone for a connection?' in
firewalld.zones(5).
[--permanent] [--zone=zone] --change-interface=interface
If the interface is under control of NetworkManager, it is at first connected to
change the zone for the connection that is using the interface. If this fails, the
zone binding is created in firewalld and the limitations below apply. For interfaces
that are not under control of NetworkManager, firewalld tries to change the ZONE
setting in the ifcfg file, if the file exists.
Change zone the interface interface is bound to to zone zone. It's basically
--remove-interface followed by --add-interface. If the interface has not been bound to
a zone before, it behaves like --add-interface. If zone is omitted, default zone will
be used.
[--permanent] [--zone=zone] --query-interface=interface
Query whether interface interface is bound to zone zone. Returns 0 if true, 1
otherwise.
[--permanent] --remove-interface=interface
If the interface is under control of NetworkManager, it is at first connected to
change the zone for the connection that is using the interface. If this fails, the
zone binding is created in firewalld and the limitations below apply.
For the addition or change of interfaces that are not under control of NetworkManager:
firewalld tries to change the ZONE setting in the ifcfg file, if an ifcfg file exists
that is using the interface.
Only for the removal of interfaces that are not under control of NetworkManager:
firewalld is not trying to change the ZONE setting in the ifcfg file. This is needed
to make sure that an ifdown of the interface will not result in a reset of the zone
setting to the default zone. Only the zone binding is then removed in firewalld then.
Remove binding of interface interface from zone it was previously added to.
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 or a MAC address or an ipset with the ipset: prefix. 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]|MAC|ipset:ipset
Bind the source to zone zone. If zone is omitted, default zone will be used.
[--zone=zone] --change-source=source[/mask]|MAC|ipset:ipset
Change zone the source is bound to to zone zone. It's basically --remove-source
followed by --add-source. If the source has not been bound to a zone before, it
behaves like --add-source. If zone is omitted, default zone will be used.
[--permanent] [--zone=zone] --query-source=source[/mask]|MAC|ipset:ipset
Query whether the source is bound to the zone zone. Returns 0 if true, 1 otherwise.
[--permanent] --remove-source=source[/mask]|MAC|ipset:ipset
Remove binding of the source from zone it was previously added to.

Direct Options
DEPRECATED
The direct interface has been deprecated. It will be removed in a future release. It
is superseded by policies, see firewalld.policies(5).
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'.
Warning: Direct rules behavior is different depending on the value of FirewallBackend. See
CAVEATS in firewalld.direct(5).
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. Make sure there's no other chain with
this name already.
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 chain with name chain from table table. Only chains previously added with
--direct --add-chain can be removed this way.
[--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. This option concerns only rules previously added with --direct
--add-rule.
[--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. This option concerns only rules previously added with --direct
--add-rule.
[--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.
Only rules previously added with --direct --add-rule can be removed this way.
[--permanent] --direct --remove-rules { ipv4 | ipv6 | eb } table chain
Remove all rules in the chain with name chain exists in table table. This option
concerns only rules previously added with --direct --add-rule in this chain.
[--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. This option concerns only rules
previously added with --direct --add-rule.
--direct --passthrough { ipv4 | ipv6 | eb } args
Pass a command through to the firewall. args can be all iptables, ip6tables and
ebtables command line arguments. This command is untracked, which means that firewalld
is not able to provide information about this command later on, also not a listing of
the untracked passthoughs.
[--permanent] --direct --get-all-passthroughs
Get all passthrough rules as a newline separated list of the ipv value and arguments.
[--permanent] --direct --get-passthroughs { ipv4 | ipv6 | eb }
Get all 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 passthrough rule with the arguments args for the ipv value.
[--permanent] --direct --remove-passthrough { ipv4 | ipv6 | eb } args
Remove a passthrough rule with the arguments args for the ipv value.
[--permanent] --direct --query-passthrough { ipv4 | ipv6 | eb } args
Return whether a passthrough rule with the arguments args exists for the ipv value.
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
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
EXIT CODES
On success 0 is returned. On failure the output is red colored and exit code is either 2
in case of wrong command-line option usage or one of the following error codes in other
