Sure, run named on your NAT box.

The internal one could be a standard slave/secondary dns server,
forwarding only or caching only, it's pretty much up to you, although if
you are registering a domain name you do have to supply two dns servers,
which makes a case for just having it be a normal secondary dns server.

Good luck
