GUI is hell :-P It's much more simple to do it in console :-)
Read this nice chapter # 14.2.1, especially its last part: http://slackbook.org/html/security-h...-HOST-IPTABLES
ps: ask, if you'll still have any linuxquestions
ps2: there is no /etc/rc.d/rc.inet2 in Ubuntu. So, you need to write that 2 lines of commands in some start script, to execute them automatically at each boot.
