I assume you want to access a device on the LAN side of the router from the WAN ?

If so, I think you have to look at opening up a port to start with ( NAT >> Open Ports setup ) and direct it at a specific device IP on the LAN side.

NAT on routers generally do not allow any unsolicited incoming traffic - which is what you're initial RDP session will start off as.

Then, what you have to do depends on your existing filter regime. If you're already passing everything, it should work OK. If you're blocking everything going out and then only allowing through ports that you need, you will have to add RDP to the list. I think that this is port 3389.

Sorry I'm not more detailed, but as I say, it depends on what rules you already have to a very large extent.

Well to me, TELNET & RDP are quite separate things.

TELNET is purely a character stream, and how the characters are interpreted is purely down to the TELNET server.

RDP is a graphical interface.

If all you want to do is to manage your router, that's fairly easy I think. Look under "System Maintenance >> Management>>Management Setup"

You might of course need to enable the Telnet Port under "NAT >> Open Ports "

If you need to TELNET into a client on your LAN ( i.e. UNIX/LINUX box ) I suppose it's quite similar.
