What are you trying to do ? You are mixing terms that makes no sense to
me, a "router" does not care about dns-servers.


If i may guess, you have an internal rfc1918-net with NAT device among
the path to Internet, and you have a resource on the inside you want to be
visible in DNS ( for clients on the same rfc1918-net as this server).

The answer is any form of "split-dns" where the world looks slightly
different depending of where you are.

There is a whole chapter ( http://www.oreilly.com/catalog/dns4/chapter/ch11.html )
of "DNS and BIND, 4th Edition" dedicated to this subject. I suggest you
read this and decide what tradeoff's you are willing to do.
