    How to iptables save and restore

    When doing some changes in iptables, one can save before so one can restore if something go wrong.


    iptables-save > /root/working.iptables.rules


    iptables-restore < /root/working.iptables.rules


    After rules are changed and one is happy with it, it needs to be saved to survive reboot. On CentOS, its done by command "service iptables save" or "iptables-save > /etc/sysconfig/iptables"

    Is this useful / helpfull? Yes | No
    The actual iptables rules are created and customized on the command line with the command iptables for IPv4 and ip6tables for IPv6. These can be saved in a file with the command iptables-save for IPv4. These files can be loaded again with the command iptables-restore for IPv4.
