I never use the GUIs. I don't feel that, in general, they give you the functions and control you need. Nor is using a GUI good for learning what is really going on in the system, and how to properly and effectively admin a system. I suggest that you look at the iptables command. This will modify the rules directly. In fedora, once you get the rules the way you want them, run '/etc/init.d/iptables save' to update the /etc/sysconfig/iptables file. I never edit the sysconfig file by hand, although I will make copies of the file as backup.
