IPFW HAS BEEN DEPRECATED IN MAC OS X 10.7 LION.
IPFW works as usual and is a very good choice also on Lions but has been officially replaced by PF. Technically IPFW and PF work together. Connections must be allowed (=not blocked) by both firewalls in order to pass.
PF is now the default firewall in OSX. WaterRoof does not support the configuration of PF.
You can download and use the free and open source PF frontend IceFloor.

IPFW HAS BEEN COMPLETELY REMOVED FROM OS X 10.10 YOSEMITE (Developer Preview 1).
IPFW has gone forever. WaterRoof development has been discontinued today, june 5 2014.
