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.
