Are you joking? That piece of crap just puts everything into one single 
chain. I never EVER use Firewall Builder after I saw the results the 
first time.

For a BRIDGING firewall, there is absolutely NO WAY that Linux/netfilter 
can keep up with OpenBSD/pf. I doubt that Linux/netfilter can even reach 
half the performance of OpenBSD/pf.
