If a timeout is supplied, the rule will be active for the specified amount of time and will be removed automatically afterwards. This option can be specified multiple times. If zone is omitted, default zone will be used. add-protocol= protocol Īdd the protocol for zone. List protocols added for zone as a space separated list.

Return whether the port has been added for zone. The port can either be a single port number or a port range portid- portid. add-port= portid/ protocol Īdd the port for zone. A port is of the form portid/ protocol, it can be either a port and protocol pair or a port range with a protocol. List ports added for zone as a space separated list. Return whether service has been added for zone. 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. add-service= service Īdd a service for zone. List services added for zone as a space separated list.

List everything added for or enabled in zone. target is one of: default, ACCEPT, DROP, REJECT permanent -zone= zone -set-short= description permanent -zone= zone -set-description= description 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. List everything added for or enabled in all zones. Print the name of the zone the source is bound to or no zone. 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. This is a runtime and permanent change and will also reload the firewall to be able to add the logging rules. The default setting is off, which disables the logging. The possible values are: all, unicast, broadcast, multicast and off. Once you're happy with the configuration and you tested that it works the way you want, you saveĪdd 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 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. 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, NOT_RUNNING otherwise (see the section called “Exit Codes”). Check whether the firewalld daemon is active (i.e.
