The goal of FireStarter is to provide an easy to use, yet powerful, GUI tool for setting up, administrating and monitoring firewalls for Linux machines. FireStarter is made for the GNOME desktop. It can actively monitor your firewall and list any unauthorized connection attempts made to your machine in a readable table format.
