I'm curious; what is the norm for client mode these days? I was looking at
the WET11 to see just what it did and I found that rather than trying any
tricks to get the host access point to forward frames for more than one MAC
address it simply replaces the source address in all outgoing packets with
its own. It then alters ARP response packets from its clients to also show
the WET11's MAC address as their own. I have no idea if it plays similar
games to try to support other protocols than IP, though I'm sure there are
some protocols for which there is no analagous hack. Actually, even for the
IP-related protocols it would have to use some other tricks to make this work.
For example, I assume it forces the B flag on in DHCP requests to make sure the
response can get back since it can't very well change the MAC address in the
request. It's kind of scary to think about networks built with a cascade of
(possibly different) pseudo-bridges like this...
