ImageIf you’re going to use your Mac as a server connected to the internet, you’ll want to be sure it’s secure. One of the best ways to do this is by using a firewall.

WaterRoof is an IPFW firewall frontend for Mac OS X with a easy interface and many options. Start from a fresh-clean system installation and be ready in 1 minute with routing/bridging, NAT and port redirection, bandwidth limits and everything you need to fine tune your ipfw configuration.

I thought the setup wizard was especially useful.

WaterRoof is free and can be download from the developer’s website.
