Remote Desktop Connection

I have recently been experimenting with remote desktop connection and it works fine using internal ip's on my network, but when I try and connect using an ip obtained from http://whatismyip.com it does not connect. I have noticed that all computers on my network have the same ip so is there a way to specify which computer to target ? Also is it possible to leave the workstation unlocked when I disconnect from it, instead of having to unlock the client workstation unlocked ?

 

You have to port forward through any router NAT layer, as well as any software firewall to allow the connection. In addition, if you want to connect to more than one of these computers using RDC, you'll have to change the port of each succeeding workstation to a unique port number. Obviously, you can't forward a single port to more than one workstation on the LAN, that's why you need multiple ports for multiple computers.

 

Thanks What is a router NAT layer ?
