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).
[--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
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.

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.

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

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 }

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.
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

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
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 cases:
