NoobProof is a firewall configuration tool for Mac OS X, a frontend for ipfw. NoobProof has a list of services each of which can be allowed or blocked. You can also selectively allow or block specified hosts or subnets. You can add or remove services from the list, and you can create new services.

You can also tune bandwidth, manage black lists and create self-configuration tools called injectors. The first time you launch NoobProof the Wizard will help you configuring the Mac OS X firewall.
