How do I export and restore my iptables settings?

Question

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.

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 ?

This tone is a bit rude my friend :) – Valerio Bozzolan Nov 02 '22 at 14:06
