How-To needed: Port Forwarding (Routing?)

Hi,

i have a problem:

I have two Windows 2003 Servers. One (A) is connected to the internet over a
network card and on the other (B) one i have a sample webserver. The
Webserver-Computer is able to connect to the internet, thats ok, but i want
to know how it is possible that i call my website from outside and the Server
A should forward the call to Server B. I think it must be called Routing, but
i haven't found any informations.

regards
Yavuz Bogazci

If you reference Routing and remote access and NAT

Reference Windows 2003 Routing and Remote ACcess RRAS, and NAT
(network address traslation) Port forwarding.
