Newbie: Cisco 800-series - Access internal server via external IP, when using NAT?

Hi all,

I've a newbie to Cisco, but somehow I've got my 837 ADSL router working - mostly!

My router is 192.168.1.1. I have a server on the LAN as 192.168.1.150. I am using NAT.

I have setup PAT so that web-traffic comes through to the router, and that is fine.

When I try to access a website hosting on the internal server via the external address (or the domain name) I'm prompted to login to the router config!

Using a local hosts file works, e.g. having host-entries, such as:

192.168.1.150

but is there a better way? I'd like to be able to access the sites via their normal domain name and IP, if possible.

Many thanks,

Jim
