Port Redirect, Windows 7 Firewall and Remote Desktop problems
Posted on 2010-08-31
So I have mutliple computers on my network (workgroup). I am trying to set up the abiltiy to remote into them from an outside source. I have a DynDNS host service configured with my router and its working perfectly.
I have my ports forwarded to the ip addresses of the respective computers on my network (I'm using DD-WRT firmware). Computer1 port 3389 (default) Computer2 port 3390
I'm running into problems with the windows firewall and now my remote desktop is not working for either (including default port). Last night I was able to remote in to the default port (on both computers when I switched the forwarding for the ip addresses) so remote desktop is enabled on both machines.
For the Computer2 with the redirected (or changed) RDP port I have modified the registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\portnumber to decimal 3390. There is a Key entry of EH-Tcp which also has a portnumber string that is the same as RDP-Tcp 3389 (so they are originally the same value).
What is this EH-Tcp? Do I need to change both (I tried but at least I know whether I need to)?
Once I changed the RDP-Tcp port I restarted the Remote Desktop Services. However, in the windows firewall there is a rule that has exception Remote Desktop TCP-In Port 3389. The firewall exception port has not changed even though I changed it in the registry. Is there a way I can change this port in the firewall? Or do I add an additonal rule?
Now even with the firewall turned off I am unable to remote in. Both computers have passwords and I was able to remote in before. Perhaps if I can get the correct configuration the default port computer will work with the firewall off.
