Thank you for the bug report. You mentioned that the problem happens after running `iptables -F`. This command removes all the rules from the firewall (see man iptables) so it would be expected that the firewall would not work correctly after running this.
I'm going to mark this as Invalid, but if you have more information, feel free to add it. ** Changed in: ufw (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938005 Title: ufw ignores rules To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ufw/+bug/1938005/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
