Port forwarding on Windows 2003 with two NICs

Q1: I just installed a new sbs2003 with two networks.

NIC  #1   192.168.1.1 = is local to all clients
NIC #2    192.168.2.2 = is connected to the Internet DSL router

This means the Server firewall is between clients and internet.

The DSL router forwards port 3389 to a client with a static IP of 192.168.1.100 I can attach remote connection from the server to the client  (Proving client is ready)

I can remote connect from the internet to the server (proving the server is ready)

==================================================
I cannot connect from the internet through the server to the client!
==================================================

Surely some form or routing must be setup.  But where and how. I am not familiar with routing an example would be appreciated. Or is it just a firewall setting?

A1: You should enable NAT on the SBS since it has two NICs. Then do port forwarding to point port 3389 to the 192.168.1.100. You also have another two options: RWW and VPN.

Q2: Hi Robert;

Thanks for responding.

Under NAT/firewal/Network Connection (192.168.2.2) properties I double checked NAT was indeed enabled  and on the Services and Ports Tab I set the RemoteDesktop port to forward to 192.168.1.100
With the DSL router forwarding to 192.168.2.2 and the server forwarding to 192.168.1.100  ..
Voila!  IT worked.

Thanks so much!
