Specifying port in Remote Desktop Client Version 2.0
I have a windows PC behind a router that I am trying to remote desktop to from my iMac. I am using the remote desktop client v2.o which I have downloaded from http://www.microsoft.com/mac/downloads.mspx?pid=Mactopia_RDC&fid=803F9438-8DF3-4 90F-92C6-0E0F92787DB8#viewer
As I am port forwarding on the router to the PC's private IP address, I need to be able to hit port 4000 on the router. When I type in the <hostname>:4000 on the iMac's remote desktop client, it does not like the port number. Would anyone know how I can establish a connection to a port other than 3389 using the Remote Desktop Client from my iMac?
Thanks in advance.
iMac, Mac OS X (10.5.7)
