NAT with wi bridging

Using FreeBSD-STABLE from a few months ago, I've noticed some weirdness. 
If I setup wi0 routing, say, NAT'ing to a wired interface (sis0 in the case 
of Soekris boards), it works great.  However, let's say I want to NAT both 
the wireless and a wired segments together (wi0 + sis1); it brings up 
promiscuous mode, and weird problems arise.  I can see broadcast traffic on 
both interface, but unicast seems to be broken.  Before I form a more 
detailed report, has anyone else tried the above configuration with success?

P.S. I moved the list to a new mail server, it should be yield faster 
delivery times and less UCE.
