Outbound policy instead of a zone to take effect for clients. Helpers that may operate in client mode (e.g. Note: Some services define connection tracking helpers. The -timeout option is not combinable with the -permanent option. To get a list of the supported services, use firewall-cmd -get-services. The service is one of the firewalld provided services. 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. If a timeout is supplied, the rule will be active for the specified amount of time and will be removed automatically afterwards. List services added as a space separated list. ![]() ![]() permanent -set-target= targetįor zones target is one of: default, ACCEPT, DROP, REJECTįor policies target is one of: CONTINUE, ACCEPT, DROP, REJECTĭefault is similar to REJECT, but it implicitly allows ICMP packets. ![]() If both options are omitted, they affect the default zone (see -get-default-zone). If used with -zone= zone or -policy= policy option, they affect the specified zone or policy. Options in this section affect only one particular zone or policy. Options to Adapt and Query Zones and Policies Print path of the zone configuration file. Load zone default settings or report NO_DEFAULTS error. permanent -new-zone-from-file= filename Īdd a new permanent zone from a prepared zone file with an optional name override. Zone names must be alphanumeric and may additionally include characters: '_' and '-'. List everything added for or enabled in all zones. Print the name of the zone the source is bound to or no zone. get-zone-of-source= source| MAC|ipset: ipset Print the name of the zone the interface is bound to or no zone. Print predefined icmptypes as a space separated list. Print predefined services as a space separated list. Print predefined zones as a space separated list. If there are no interfaces or sources bound to the zone, the corresponding line will be omitted. Active zones are zones, that have a binding to an interface or source. Print currently active zones altogether with interfaces and sources used in these zones. Setting the default zone changes the zone for the connections or interfaces, that are using the default zone. Set default zone for connections and interfaces where no zone has been selected. Print default zone for connections and interfaces. Run checks on the permanent configuration. Once you're happy with the configuration and you tested that it works the way you want, you save The way this is supposed to work is that when configuring firewalld you do runtime changes only and Save active runtime configuration and overwrite permanent configuration with it. For example if there are state information problems that no connection can be established with correct firewall rules. This option should only be used in case of severe firewall problems. This will most likely terminate active connections, because state information is lost. Reload firewall completely, even netfilter kernel modules. Note: If FlushAllOnReload=no, runtime changes applied via the direct interface are notĪffected and will therefore stay in place until firewalld daemon If they have not been also in permanent configuration. all runtime only changes done until reload are lost with reload Reload firewall rules and keep state information.Ĭurrent permanent configuration will become new runtime configuration, This will also print the state to STDOUT. Returns an exit code 0 if it is active, RUNNING_BUT_FAILED if failure occurred on startup, NOT_RUNNING otherwise. Check whether the firewalld daemon is active (i.e. ![]()
