Just an observation...the OP asked about "bridge" functionality and you
answered the question of how to make a router.  I think you answered the
question he *meant* to ask, but I'm not sure.  If he really wanted a
bridge, that's a completely different set of instructions (as we both
know FreeBSD is perfectly capable of doing *that* too).
