I do.  I run a DNS server behind a firewall/gateway machine that is
running NAT.  My DNS machine can do lookups to the outside world, and
it can do lookups for my internal network, but of course, it can't do
lookups for the outside world to my internal network, as I am using
unroutable IPs.

I wouldn't run DNS on your firewall machine.  I prefer not to run any
services at all on my firewalls.
