I used to do that few years ago, using ip-firewall at that time
instead of ipfw, I can't remember the reason why, I think it was the
unavailability of layer 2 in IPFW at that time.

I have switched to zeroshell since because I needed captive portal too
and neither monowall nor pf sense did offer captive portal on bridged
intefaces when I did the change.

I am pretty sure that monowall and pfsense do offer bridged interfaces.

Best regards,

Olivier
