Is it possible to use remote desktop to connect to multiple computers inside a network that has a dynamic IP address?


I use a netgear WPN824 router which has dyndns onboard - but I currently use No-IP to control a single computer that I use most frequently. Every so often I need to get onto a couple of other computers in the network, but don't know how to go about this without logging onto one computer, and then starting another RDC session from that machine.

What I would like to be able to do is connect to my router, and be able to see a list of connected devices, and then choose which to remote desktop onto. - I appreciate this probably is not be possible, but any other suggestions are welcome!

Define multiple port forwardings on your router. E.g. If you have three machines (a,b,c), you forward it like this:

router:33901 -> a:3390
router:33902 -> b:3390
router:33903 -> c:3390

When you want to connect (let's say to a), just use

external.dyndns.org:33901

as rdp address.

Change the default RDP port for each of your other machines. The number must be unique for each machine. Then apply port forward rules on your router to connect to the individually assigned inside IP addresses.

When you open the Remote Desktop Connection client from outside use the same no-ip assignment that you use for your primary connection but just add :#### for what ever port number you assigned to the machine you want to connect to.

So if I start a remote desktop session, I type in username@dyndns.org:portnumber ? is that correct? –  falter Sep 4 '09 at 12:17
    
Yes, I typically use ports 5965-5969 –  Duey Sep 4 '09 at 12:20
