Default Re: DHCP over a dd-wrt client bridge.

Retch. DHCP *SHOULD* work through a wireless bridge (if it will pass
broadcast packets). Using WDS seems like a band-aid or work around
for a bug. I have a funny feeling there's some interaction with WOL
(Wake on LAN) which also uses an all 1's broadcast packet. If the
micro version supports WOL, try turning it on and see if it now passes
broadcast packets. You can also use a WOL client to generate
broadcasts to 255.255.255.255 to see if they make it through the
bridge.

If you get a usable answer from the DD-WRT folks, I would be
interested.

Hmmm... I just checked the Bug Tracker and couldn't find anything
directly related to v25 RC4 and DHCP. There are a few DHCP bug
reports, but I'm discounting any reports without corroberating details
(i.e. clueless bug report). I don't see anything on the most recent
50 bug reports:
