Check your router's documentation. The way that 99% of these routers are set 
up, is that they run a caching nameserver internally, and on the local LAN 
they give their own IP address as the DNS server's address, via DHCP.

Chances are that this is unnecessary. You should've just set your servers to 
use your router as the DNS server.

Why don't you test setting your server as full blown DHCP client, and see 
what DNS address your router gives you for your DNS server. Chances are that 
it's your router's IP address. In which case you just need to configure your 
servers to use a static DNS server on your router's IP address.
