[gentoo-user] modifying iptables: how can I prevent locking me out?

[Jarry]

Hi,

I have to change rather complex iptables rules on server
and I do not want to lock me out as this server is about
50 miles away. So how should I do it?

I can back up the old rules by running:
/etc/init.d/iptables save
and it will be saved to /var/lib/iptables/rules-save
(some strange format starting with number like [536:119208])

I prepared a script with new (modified) iptables-rules,
which I will run in bash. But in case I screw something,
how could I force netfilter to load old saved rules,
if I for whatever reason do not connect to server (ssh)?

Or can I load new iptables-rules for certain time, and
then force netfilter to load back the old rules again?
