SBS 2003 SP2 configured with 2 Nics, internet connection is connected directly to a speedstream modem, the other connected to the internal network switch. I am able to remote desktop into the server, I want to remote desktop into one of the client computers behind the server firewall. I have changed the client listening port to 3390 and opened port 3390 via Routing and Remote access. I then run the open port check tool via canyouseeme.org and the port is not open. Is there another setting I need to make to open port?
