WaterRoof is an IPFW firewall frontend for Mac OS X with a easy interface and many options. Features include dynamic rules, bandwidth management, NAT configuration and port redirection, pre-defined rule sets and a Wizard for easy configuration. You can also watch logs and graphic statistics. Rules configurations and network options can be saved and optionally activated at boot time.
With WaterRoof setting up a dual-homed firewall with Mac OS X has never been so easy... 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. And every option can be easily set to be loaded at boot time, leaving you nothing else to do (except mailing me bug reports ;)
English documentation included into the application bundle. You access it from the WaterRoof "Help" menu.
