netfilter-persistent and its plugins
------------------------------------

netfilter-persistent does no work on its own. You need the accompanying
plugins (for example, iptables-persistent) to load and save filter rules.

However, commands are run from netfilter-persistent. For example, to save
all filter rules:

   netfilter-persistent save

or to load them:

   netfilter-persistent start

For more details, see `man netfilter-persistent`.

The system service will try to load rules at startup if enabled, but by
default it will not flush rules at shutdown. This behaviour can be changed
by editing /etc/default/netfilter-persistent.
