Yep. I was going try and find that thread. Note that about half the
repies indicate that DHCP should work behind a DD-WRT client.
Unfortunately, there are about an equal number of "it works" and "it
doesn't work" posting, with little substantiations. Even if there was
some complication with assigning multiple IP's to a single MAC
(perfectly legal as in multi-homed) you would still get at least *ONE*
DHCP assigned IP address to the first client to connect.

Also note item 6 in the first article:
... The main router will handle DHCP for any and all devices
connected, whether it be on the normal wlan or behind the
client bridge - it won't matter which.
In other words, DHCP should work.

Look at the 2nd reply in that article... the one that lists the output
of arp -a for a transparent bridge and for DD-WRT in client mode. Note
that the 2nd apr -a example, for the DD-WRT client, shows multipile
IP's for a single MAC. However, also note that all the entries are
listed as "dynamic" which means they came from a DHCP server
somewhere.

Now, there's a possibility that the author faked the results, or has a
DHCP server running on his client, or some other oddity, but it would
appear that DHCP worked for him with DD-WRT.

Incidentally, I've never heard of semi-MAC-Address-Translation (MAT)
or a MAC proxy. I couldn't find anything on it with Google. Weird.

These might be worth digesting:
