Access multiple machines externally via RDP

Question

I currently port forward port 3389 on my router to the internal IP address of the machine I want to RDP to the most.

I really want to be able to RDP from external to many internal machines.

Can anyone suggest a list / range of ports I could use?

Thanks Paul

There's 2 ways to do this easily

• the first is to set up a terminal services gateway server - this will act as a proxy to the internal machines and let you connect to them via the gateway (recent versions of SBS have this as standard)

• the second is to setup multiple external ports (can be anything) forwarding to the different machines on 3389. This should be possible but will depend on your firewall, for example:

  if 123.123.123.123 is your external ip, and 192.168.0.0/24 is your internal range,

  forward 123.123.123.123 port 3389 -> 192.168.0.1 port 3389

  forward 123.123.123.123 port 3390 -> 192.168.0.2 port 3389

  forward 123.123.123.123 port 3391 -> 192.168.0.3 port 3389

  then connect to each one through the normal rdp client as:

  123.123.123.123:3389

  123.123.123.123:3390

  123.123.123.123:3391
