I have what appears to be weird and convoluted set of rules which work for me at the moment. Is there a way of "exporting" those and saving them to a file so that they can be restored later on in case things are messed up?

With suitable privilege
iptables-save > /some/file
will save your iptables configuration to /some/file
and
iptables-restore < /some/file
will restore your saved configuration from /some/file
.

Ah... I didnt know of those. I kept looking for some command line options! Sep 23, 2010 at 0:43
This should do the trick. It writes your rules to /etc/sysconfig/iptables; if you (re)start iptables after you do this, your rules should be there :)
/sbin/service iptables save
Don't you have iptables-save
and iptables-restore
commands ?
