Copy UFW rules between servers
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?
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.
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
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
