try GuardDog... It's a nice GUI that works with IPfilters (the default firewall for Mandrake I believe)
It has some nice sections that help you open up certain ports. Should be familiar if you've done much firewalling in windows.
BTW, Mandrake is a great distro to start with. Have you looked into the Penguin Liberation Front? They make prebuilt P2P and multimedia packages for Mandrake and even have a urpmi repository. Go check out their site if you need explination.
