wireless <=> wired bridge & dhcp?

Hello Folks
I've checked out the basic set up and done a fair bit of googling.
With Wireless Bridge mode the dhcp server won't work (correct?).
With Client mode the dhcp server only serves the wired lan (correct?)
I'm not interested in bridging to other wireless devices, all I want is to provide a wireless to wired bridge and serve the whole combined single subnet with the dhcp server. Are there any configurations other than Wireless Bridge (which includes extending the network to other wireless devices, correct?) and Client (which doesn't include serving to other wireless devices, correct?) modes that allow extending a wireless network to a wired network while continuing to serve dhcp leases over the whole network?
Many thanks,
Morgan.

DHCP should be disabled to avoid problems if you want to use your router as wireless bridge.. otherwise, you can access internet but you will not be able to access your LAN.
Read the section on "Bridged Client Mode (with relayd)"
http://wiki.openwrt.org/doc/howto/clientmode
This is probably what you want to do...

Hi ispyisail & eric
Thanks for getting back and sorry for the late follow up - had an exam last week...
ispyisail - the diagrams where eric pointed show what I'm after:
http://wiki.openwrt.org/doc/howto/clien ... m-2.4.only
And, eric & ispyisail, yes - "Bridged Client Mode (with relayd)" is probably what I want, but also perhaps "Bridged Client Mode (brcm-2.4 only)" because I notice here:
http://wiki.openwrt.org/doc/howto/clien ... ode.issues
at para 2
That Gargoyle has support for other than brcm-2.4 routers - is that possible here?
And, I see here:
http://wiki.openwrt.org/doc/recipes/rel ... hcp.server
"Bridged Client Mode (with relayd)" disables DHCP because the DHCP requests from LAN will be answered by the wireless AP the router it is connecting to.
But, I have disabled the DHCP (with DNS info) server on my wireless AP and have been using the DHCP server on my Gargoyle wrt54g instead. (That's because my wireless AP just happens to be a VirginMedia pile of poo called a Super(sub)Hub that VM uses to hijack my DNS requests and advertise their stuff - sorry for the rant.) So, if I'm not using DHCP on my wireless AP, can I continue to use the DHCP on the Gargoyle wrt54g?
Many thanks,
M.
[edit]
PS I've implement "Wireless Bridge/Repeater " as per instructions here:
http://www.gargoyle-router.com/wiki/dok ... figuration
And it seems to work as expected - minus DHCP .
Is this the "Bridged Client Mode (brcm-2.4 only)" described here:
http://wiki.openwrt.org/doc/howto/clien ... m-2.4.only
With the 3rd-party patches to implement ARP-NAT for platforms other than brcm-2.4 described here:
http://wiki.openwrt.org/doc/howto/clien ... n.brcm-2.4
The Gargoyle "Wireless Bridge/Repeater " implementation?
