Scenario: we are an ultrasmall company with an ultrasmall network. We have AT&T DSL at the office with a WRT54GL router running DD-WRT, and a Windows 2003 Server box for AD. I forward LAN DNS requests to the AD box for resolution. Our simple network is a class C network.

We have an extra domain name laying around, and we want to forward that to a particular server on our private network. For example: I want forward all requests to dev1.testdomain.com and dev2.testdomain.com from the internet to particular servers on our private network.

I created a name server entry, ns.testdomain.com, pointing to the static IP address of our DSL and I already set the name server of testdomain.com to ns.testdomain.com. Where do I go from here? How do I get the Windows AD box to understand and route the traffic accordingly?

Is this even possible? Thanks, all.
