How to save/restore iptables rules
We can take the backup of existing rules in the iptables firewall using the following command.
#iptables-save > /root/backup.iptables.rules
Now all the rules will be stored to the file '/root/backup.iptables.rules'.
The backed up rules can be restored at any time using the below command.
#iptables-restore < /root/backup.iptables.rules
That's all.....
