How do I export and restore my iptables settings?

  • 772

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?

linux redhat iptables

    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.

  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

  3. Don't you have iptables-save and iptables-restore commands ?
