Configure Cisco Router 2811 to Act as DNS server

Hello Experts

Can someone show me how to configure a cisco router to act as dns server.
I currently have server that can connect to the internet via the router from a private ip address. However, I can't connect to server using its hostname from the internet. I believe it was because the server had not been configured with the appropriate dns settings. Therefore, I configure the dns settings with the ip address of the router 192.168.1.x. Now I need to configure the router to act as a dns server with the public ip address of 84.45.116.x.

The server is windows 2003.

You're help will be greatly appreciated.

Cheers

Carlton

Well, it sounds like what you want is a public dns entry for the external address.

for instance a web server may have a www record configured in the dns for www.mydomain.com that relates to its IP.

So, two things, if you have a domain name, whoever you have that hosted with (network solutions, etc) will let you create an alias record for the www address

on the router, you'll need to create a static mapping or to allow whatever traffic you want inside.
