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.
