Just picked up a Netgear wireless router. I use NAT so that all the devices connected to it have an internal IP address. How do I set it up to allow incoming Remote Desktop connectionr requests (port 3389)?

There are several options in the router: DMZ, port triggering, port forwarding, etc.

My laptop has a permanent IP address within the internal network, if that helps anyone. There should be a simple way to say "incoming requests on port 3389 should be forwarded to xxx.xxx.xxx.xxx (laptop)."

I believe it would be port triggering. The router's description:


Port Triggering is used to allow applications which would otherwise be blocked by the firewall. Using this feature requires that you know the port numbers used by the Application.

Once configured, operation is as follows:

A PC makes an outgoing connection using a port number defined in the Port Triggering table.
This Router records this connection, opens the INCOMING port or ports associated with this entry in the Port Triggering table, and associates them with the PC.
The remote system receives the PCs request, and responds using a different port number.
This Router matches the response to the previous request, and forwards the response to the PC.
(Without Port Triggering, this response would be treated as a new connection request rather than a response. As such, it would be handled in accordance with the Port Forwarding rules.)

Note

Only 1 PC can use a "Port Triggering" application at any time.
After a PC has finished using a "Port Triggering" application, there is a "Time-out" period before the application can be used by another PC. This is required because this Router cannot be sure when the application has terminated.
You can enter a name for the rule, outgoing (trigger) port range, and incoming (response) port range. You cannot point it to a specific machine.

Port forwarding, on the other hand, lets you provide a name, starting port, ending port, and "server IP address" (the laptop's static IP??). Router's description of port forwarding:


Using the Port Forwarding page, you can make local computers or servers available to the Internet for different services (for example, FTP or HTTP), to play Internet games (like Quake III), or to use Internet applications (like CUseeMe). For the services, applications, or games, that already exist in the pull-down list, you'll only need to specify the computer's IP address. Otherwise, the port number and computer's IP address for each service, game or application should be specified by clicking the Add Custom Service button.

You're going to want to use port forwarding, with the "server IP" being your laptop's IP address.
Port forwarding actually opens the port to the world.
Port triggering opens the port to the world, but only if a program in the local computer attempts to use that port first.

Yeah, what he said.
