Prints a short help text and exits.

Print the version string of firewalld. This option is not combinable with other options.

Do not print status messages.

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 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.

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.

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.

Print the log denied setting.

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.

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.

Print default zone for connections and interfaces.

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.

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 ..

zone3
  sources: source2 ..
	      

If there are no interfaces or sources bound to the zone, the corresponding line will be omitted.

List interfaces that are bound to zone zone as a space separated list. If zone is omitted, default zone will be used.

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).

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.

Query whether interface interface is bound to zone zone. Returns 0 if true, 1 otherwise.

Get all chains added to all tables. This option concerns only chains previously added with --direct --add-chain.

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.

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.

Remove chain with name chain from table table. Only chains previously added with --direct --add-chain can be removed this way.

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.

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.

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.

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.

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.

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.

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.
