Mac OSX server not supported behind ...

For a customer, I recently installed a new XServe, within a local network with an Airport Extreme (n) with FW 7.4.2. Mac OSX Server manages the router (which has a fixed IP from the ISP). Because the Mac OSX Server runs a DNS server (supporting a local domain), OSX Server reconfigured the Airport Extreme, so that it would forward DNS queries to the server. The server's dns server will forward queries for non-local domains to the ISP's dns servers.

All clients get their IP configuration using DHCP from the router. You can't use the DHCP service of the server, as you can't disable DHCP on the router (in NAT mode).

All clients get the router's IP as the dns server.

HOWEVER:

The Airport Extreme can't connect to the internal DNS server! It doesn't seem to be able to route dns requests to the internal network (verified using nslookup). Any dns queries sent to the router will time out.

Come on, Airport Extreme team.. you can't claim the Airport Extreme to be the ideal router in combination with an OSX server, if this simple and very common setup is not supported! How hard can it be to either:

...Allow us to disable DHCP on the router (even when in NAT mode), so we can use the OSX server for this (which will dispatch the correct DNS settings)
...Allow the router to route DNS queries to the local DNS (OSX) server (which should be working anyway)
