Topic: access net device on INTIF over wireless bridge

Here's the setup.  FYI pretty large resort,

Cable<-->Office Lan <--> Chilli <---> North Side VDSL <--> South VDSL             (North VDSL has 14 AP's South has 18 AP's)

I have configured DVR's to work on the INTIF side and we have access to them. This works fine, but we have 1 that can not get VDSL to it. Ideally I should be able to put a wireless bridge between one of the AP's and the DVR. However DHCP is then lost. If I hook my laptop to it after being connected it will then use a preferred IP and connect to net as expected. I can communicate with the AP that is used for the bridge, but can not get DHCP to follow through the wireless bridge.

Anybody had to use this type scenario?

My next idea is use OPEN VPN on  the AP that is used for the bridge. Has anybody tried this?
