This has been discussed here a few times in the past, but there's some
interaction between the NAT-ing and the bridging that makes this not
work. It's not a m0n0wall problem per se, in that if you were to try
this with a generic FreeBSD system with IPFilter and bridge(4), you'd
run into the same problem.
