Yes, I'm sure. Turns out that ufw is just a simpler interface to iptables, and ufw allows that: sudo ufw allow <service name> (that was from https://help.ubuntu.com/community/UFW#Allow%20and%20Deny) > Creating a firewall which dynamically changes is probably not possible > with a GUI! /etc/hosts.allow does allow to include either IPs, or domain names. But if the IP can change, you can end up blocking the current ip and allowing for a different one, so you have to do as you do. But once you've solved it, it can be a feature in a GUI any day.
