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.
