These are all the same subnet. The Router has nothing to do with any of
this. A wired Bridge (a Layer2 device) would also have nothing to do with
it,...but since this is a wireless Bridge that uses additional security due
to the fact that it is wireless, that secureity stuff may be getting in the
way.
DHCP is totally passive,...it does not contact the clients. It is the
Clients that always contact it,...and they do so via broadcasting which
should work unrestricted since this is all a single IP Segment (geography
means nothing). So you may have to run NetMonitor or other sniffer on the
DHCP box and see if it is actually receiving the DHCP Query broadcasts from
the "troublesome" clients.
Also keep in mind that just because you use DHCP doesn't mean that
everything has to use it. Typically hosts that are over a WAN Link may run
static addresses (IP# range listed in "Exclutions" in the Scope) so that the
machines will continue to "stay alive" even if the WAN Link goes down for a
period of time.
For similar reasons there is usually a DC at each physical location as well.
The AD Sites object is used to control AD Replication over the slow WAN
Link. The Sites Object requires that each physical Site have a unique
Subnet with Layer3 Routers between the Sites instead of using Bridges. But
the idea is that the local DC keeps things running at the Site even if the
WAN Link goes down. The DC typically also runs DHCP for that particular
Site & IP Segment, so the Hosts get their IP Config locally at their Site.
