I don't use IPFW and IPFilter together, but IIRC IPFilter steps between everything else (except for bpf) and the interface. Same for IPNAT, which integrates with IPFilter. Since the advent of pf and altq, OpenBSD has had a better firewall architecture than any of the other BSDs, IMHO. pf can do things which are awkward in other systems because features were kludged in later. I've always thought that it would be cool to be able to integrate firewall components into FreeBSD via its unique NetGraph system. This would let you filter specific flows of packets very efficiently. --Brett
