How do I export and restore my iptables settings?
Solution 1:
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.
Solution 2:
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
Solution 3:
Don't you have iptables-save and iptables-restore commands ?
