the "can't bridge LAN to anything else" makes it real tough to create a
with a single Ethernet and WiFi device.
In particular, if you run the WRAP.2C board (single Ethernet) with a
single 802.11 NIC, you
can't bridge the two.
So consider this an "enhancement request".

assuming that the 802.1d (spanning tree) works, then frames should only
be sent to the interface
where the destination address has already appeared as a source address.
If no interface matches, then the frame gets sent "everywhere" (except
the originating interface).
If the dest is a group addressed frame, then the frame should get copied
to all the other interfaces.
There is no multicast IP support beyond that in m0n0wall. (Though it
would be a great add for pfSense.)
