I know its layer 3 ... my point is that FreeBSD's bridge supports IPFW, 
and IPFW allows for some IP-related things ...filtering by source IP, 
destination IP, etc. etc.  But in the man page for ipfw, it says that 
the "forward" command in ipfw is not supported on layer 2 (bridging, 
etc.).  So I was wondering if there was a way to forward specific IP 
traffic without using NAT or routing (just strictly bridging).  Someone 
on IRC mentioned that its possible, but would require a custom program....

Thanks,

-Matt
