Guest Jason Posted September 28, 2008 Posted September 28, 2008 I see RDC uses UDP and port 3389. Initially I thought I just needed to forward TCP port 3389 from the router to the computer. So do I need to forward UDP port 3389 as well? Is there other ports that need to be forwarded as well? I've used RDC over a LAN ok but haven't been able to over the internet where the host computer is conencted via an ethernet router. Thanks, J.

TCP Port 3389 is sufficient and no other ports are required. Start by running some tests with this command: telnet IPAddress 3389 first on your LAN, then via the Internet. Note that you must use your router's external IP address for these tests, not the PC's internal address.
Guest Jason Posted September 28, 2008 Posted September 28, 2008 Re: Remote Desktop connection I was using the routers internet IP address/internet domain name address but still couldn't connect. Over the LAN worked fine.

Over the LAN worked fine. Your router is not forwarding the packets it receives, perhaps because the forwarding rule is incorrect or because of some firewall restriction. Use the telnet command I quoted before to test the connection.

Remote Desktop worked fine over the LAN but I had no luck connecting from a remote location. When I hit the Connect button the RDC program just closed. No error message. This was in an office where RDC worked on older computers fine. That meant the router settings were OK. The new computers also had the same firewall settings. I did a little research and ran into a bunch of references to Nvidia and ATI video drivers being the source of the problem. I installed the latest drivers from Dell's web site but that didn't help. It wasn't until I installed the latest drivers from ATI's web site that I was able to get RDC working. Nepatsfan
