Opening up Netgear Router for RDP Access

I have an SBS server connected to the the internet via a Netgear dg834 router. This server has 2 network cards and also has ISA server installed.

I believe that because ISA is installed, I can't use UPNP to configure the router. I need to get port 3389 opened so I can administer the server remotely. I have manually done this on the router and there is a rule in place in ISA to allow RDP access.

So why can't I login externally with Terminal Services?

Test if your Netgear rule is working first.  Place another computer behind the netgear, and test if RDP works when trying to connect to that machine.  If that does work, then you know it is something with the ISA rule......if it doesn't work, then you have to start your troubleshooting from the Router first....

Never thought of that. Unfortunately I won't be at that customer's again until Monday. So watch this space..

You need to set up port forwerding on the Netgear router, so that it forwards port 3389 to your internal server.  WARNING this opens you to the posibility of attack.  A better solution would be to create a VPN to the netgear router.  You can do this with the VPN client that netgear has (I think it's about 50.00).  This will provide you with encryption between your client and the remote desktop as well as require some authentication before entering the network.  Also you will beable to connect to any internal network resources.

This is whacky, but several hours later, and without my intervention. it's started working. I tried for a couple of hours earlier today and couldn't make it work at all.

So thanks for your replies. I've split the points between you.
