FIREWALL-CMD(1) firewall-cmd FIREWALL-CMD(1)
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
For sequence options, this are the options that can be specified multiple times, the exit code is 0 if there
is at least one item that succeded. 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,
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.
--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.
--get-log-denied
Print the log denied setting.
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.

[--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

zone
interfaces: interface1 ..
[--permanent] --list-all-zones
List everything added for or enabled in all zones. The output format is:

Remove rich language rule 'rule' from zone. This option can be specified multiple times. If zone is
omitted, default zone will be used.
For the rich language rule syntax, please have a look at firewalld.richlanguage(5).
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).
[--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 addion 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
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

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.

Add a new chain with name chain to table table. Make sure there's no other chain with this name already.
[--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

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.

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.

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.
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.
--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.

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
