NAME

       netfilter-persistent - load, flush and save netfilter rule sets

SYNOPSIS

       netfilter-persistent start

       netfilter-persistent stop

       netfilter-persistent flush

       netfilter-persistent save

DESCRIPTION

       netfilter-persistent uses a set of plugins to load, flush and save netfilter rules at boot
       and  halt  time.   Plugins  can  be  written  in  any  suitable  language  and  stored  in
       /usr/share/netfilter-persistent/plugins.d

OPTIONS

       start  Calls  all  plugins  with the start argument, causing them to load their rules into
              netfilter.

       stop   If the configuration FLUSH_ON_STOP is enabled, calls all  plugins  with  the  flush
              argument,  causing  them  to remove their rules from netfilter.  Otherwise, emits a
              warning only.

       flush  Calls all plugins with the flush argument, causing them to remove their rules  from
              netfilter.

       save   Calls all plugins with the save argument, causing them to save the currently-loaded
              rules to persistent storage.

PLUGINS

       Plugins can be written in any language and are  merely  executed  by  netfilter-persistent
       with   a   single   argument.    All   plugins   are   stored   in   /usr/share/netfilter-
       persistent/plugins.d

       Plugins must implement the start flush and save arguments and must not rely on  additional
       arguments for other functionality.
       Plugins must return 0 on success and any other code on failure.

       Plugins  are free to use and extend the configuration in /etc/default/netfilter-persistent
       and to implement their own configuration files.
