Thanks for the bug report. A few things: 1. I'm not sure what 'networking stops' means precisely in the context of this bug report. Does 'ufw disable' restore the network? Is the network torn down? Something else (you are using a lot of limit rules instead of allow rules, I wonder if you are hitting limits...)?
2. 'journalctl -u ufw.service' isn't normally going to show you much since the command run from the service isn't very chatty. Better would be to look at /var/log/ufw.log around the time the networking stops. If /var/log/ufw.log doesn't exist on your distro, you should check /var/log/kern.log for firewall denials and then try to resolve them with new/modified firewall rules 3. It isn't clear if you used the check-requirements from https://git.launchpad.net/ufw/tree/tests/check-requirements or the one on the system. Which did you use? (Note, I just made a change to https://git.launchpad.net/ufw/tree/tests/check-requirements that you might want to use) 4. you didn't mention which distro you are using, but the ufw.service file is not what is shipped upstream (or Ubuntu or Debian). This is what has been shipped in Ubuntu and Debian for several years: [Unit] Description=Uncomplicated firewall Documentation=man:ufw(8) DefaultDependencies=no Before=network.target [Service] Type=oneshot RemainAfterExit=yes ExecStart=/lib/ufw/ufw-init start quiet ExecStop=/lib/ufw/ufw-init stop [Install] WantedBy=multi-user.target and this is what is upstream (Debian is the same except omits the 'Conflicts') and what should solve some issues (though I'm not sure it would solve your issues: [Unit] Description=Uncomplicated firewall Documentation=man:ufw(8) Before=network-pre.target Wants=network-pre.target Conflicts=iptables.service ip6tables.service nftables.service firewalld.service [Service] Type=oneshot RemainAfterExit=yes ExecStart=/lib/ufw/ufw-init start quiet ExecStop=/lib/ufw/ufw-init stop [Install] WantedBy=multi-user.target You may want to adjust the service file to be like the upstream one, then run 'sudo systemctl daemon-reload' and reboot. ** Changed in: ufw (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1956029 Title: ufw remains inactive at boot time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ufw/+bug/1956029/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
