I'm doing a hardware refresh on a my Colo, I just need to copy my UFW rules from my old server to my new server. I dont seem to be able to get them copy all the active rules from my old server to my new one.

How do I copy my active UFW rules between servers?

firewall ufw

    I found the rules in /etc/ufw/user.rules and for ipv6 you can find the rules in /etc/ufw/user6.rules.

    If you copy those files between the servers, disable and then re-enable ufw.

  2. User configurations for UFW should be in /etc/ufw. You are not supposed to modify files in /lib nor /usr/lib nor any other similar locations, because your modifications might get overwritten by the vendor's default version after the packages upgraded.

    From Ubuntu 16.04:

    ls /etc/ufw

    after6.rules applications.d before.rules user6.rules
    after.init before6.rules sysctl.conf user.rules
    after.rules before.init ufw.conf

  3. Those /lib/ufw/user.rules /lib/ufw/user6.rules are just symlinks to /etc/ufw/user...

    Copy those files from and to /etc/ufw directory

  4. Another solution could be:

    Save current config with:

    iptables-save >/to/some/filename

    Then restore it with:

    iptables-restore </to/some/filename
