cannot connect to internal servers with NAT

[Guest]

Hi,

I have setup a win2003 server with NAT as a router for my internal network.
Everything works fine such that all my internal network can connect to the
internet. However, when I setup the public interface to open up a few
services from my internal network through "Services and Ports", I can't get
to any of those ports that I opened. It works ONLY if the port is opened on
this win2003 server, but not if it is to another server on my private
network. It seems as if my public interface doesn't know how to get to
computers in my private network.

Please advise on what I have to do in order to solve this? Perhaps adding a
route from my public interface to my entire private network?

Thanks!

You can only use a port on a LAN machine from an external source if you
have forwarded that port to a particular internal IP address. So if you
forward port 80 to 192.168.0.13, you can use 192.168.0.13 as a webserver
visible from the Internet.

You configure port forwarding in the NAT section of the RRAS console.
