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! –  siliconpi Sep 23 '10 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 ?
