-h,  --help

Prints a short help text and exits.

-V,  --version

Prints the version string of firewalld and exits.

-q,  --quiet

Do not print status messages.

--default-config

Path to firewalld default configuration. This usually defaults to /usr/lib/firewalld.

--system-config

Path to firewalld system (user) configuration. This usually defaults to /etc/firewalld.

--enabled

Enable the firewall. This option is a default option and will activate the firewall if not already enabled as long as the option --disabled is not given.

--disabled

Disable the firewall by disabling the firewalld service.

--check-config

Run checks on the permanent (default and system) configuration. This includes XML validity and semantics.

This is may be used with --system-config to check the validity of handwritten configuration files before copying them to the standard location.

--reset-to-defaults

Reset configuration to firewalld's default configuration

These options are nearly identical to the options of lokkit.

--migrate-system-config-firewall=file

Migrate system-config-firewall configuration from the given file. No further

--addmodule=module

This option will result in a warning message and will be ignored.

Handling of netfilter helpers has been merged into services completely. Adding or removing netfilter helpers outside of services is therefore not needed anymore. For more information on handling netfilter helpers in services, please have a look at firewalld.zone(5).

--removemodule

This option will result in a warning message and will be ignored.

Handling of netfilter helpers has been merged into services completely. Adding or removing netfilter helpers outside of services is therefore not needed anymore. For more information on handling netfilter helpers in services, please have a look at firewalld.zone(5).

--remove-service=service

Add the port to the default zone. This option can be specified multiple times.

The port can either be a single port number or a port range portid-portid. The protocol can either be tcp, udp, sctp or dccp.

-t interface, --trust=interface

This option will result in a warning message.

Mark an interface as trusted. This option can be specified multiple times. The interface will be bound to the trusted zone.

If the interface is used in a NetworkManager managed connection or if there is an ifcfg file for this interface, the zone will be changed to the zone defined in the configuration as soon as it gets activated. To change the zone of a connection use nm-connection-editor and set the zone to trusted, for an ifcfg file, use an editor and add "ZONE=trusted". If the zone is not defined in the ifcfg file, the firewalld default zone will be used.

-m interface, --masq=interface

This option will result in a warning message.

Masquerading will be enabled in the default zone. The interface argument will be ignored. This is for IPv4 only.

--custom-rules=[type:][table:]filename

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.

--get-default-zone

Add a service. This option can be specified multiple times.

The service is one of the firewalld provided services. To get a list of the supported services, use firewall-cmd --get-services.

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 --new-policy clientConntrack
# firewall-cmd --policy clientConntrack --add-ingress-zone HOST
# firewall-cmd --policy clientConntrack --add-egress-zone ANY
# firewall-cmd --policy clientConntrack --add-service tftp

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)).

--direct --get-all-chains

Get all chains added to all tables.

This option concerns only chains previously added with --direct --add-chain.

--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.

--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.

--direct --remove-chain { ipv4 | ipv6 | eb } table chain

Remove the chain with name chain from table table.

--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.

--direct --get-all-rules

Get all rules added to all chains in all tables as a newline separated list of the priority and arguments.

--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.

--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.

--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.

--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.

--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 --get-all-passthroughs

Get all permanent passthrough as a newline separated list of the ipv value and arguments.

--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.

--direct --add-passthrough { ipv4 | ipv6 | eb } args

Add a permanent passthrough rule with the arguments args for the ipv value.

--direct --remove-passthrough { ipv4 | ipv6 | eb } args

Remove a permanent passthrough rule with the arguments args for the ipv value.

--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.

--policy-server

Change Polkit actions to 'server' (more restricted)

--policy-desktop

Change Polkit actions to 'desktop' (less restricted)
