port forwarding on netgear DGND3700v2
Hi All,
I am having major trouble port forwarding on the DGND3700v2 router. I have never used this router before and just wondering if anyone knows how to do this sucessfully, everything I have tried just does not work.
All I want to do is set up remote desktop connections to the 5 or so computers I have behind the router. Any ideas what I'm doing wrong?

Thanks. How would I make the computers listen on different ports and set up the ports for them on port forwarding
You could set the router to forward an external (incoming) port to a particular computer.
For example,
TCP port 12000 point to 192.168.1.5
12001 to 192.168.1.6
12002 to 192.168.1.7 etc.....
So when remoting in, add the port, i.e,
xxx.xxx.xxx.xxx:12001 would be the "computer" in the Remote Desktop Connection input
If your ip is dynamic, you can use a service like dyndns.com to use a hostname instead of a IP that will change.
So then for your "computer" you can use something like hostname.dyndns.org:12001 this would remote into 192.168.1.6 (as above)

i use this method for RDP for an office of 25 and at my home of 3. It's a great method, works well.
If you have the need to access multiple computers or resources inside your network from the Internet then you should consider a VPN.
But here's how to change the RDP port number. Leave one of them at default port, which is 3389, then change the other 4 each to a different port. 3390, 3391, 3392, 3393 should work if nothing else is binding to those ports.
From Microsoft (http://support.microsoft.com/kb/306759):
Start Registry Editor.
Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\System\
On the Edit menu, click Modify, and then click Decimal.
Type the new port number, and then click OK.
Quit Registry Editor.
Restart the computer.
Then do the port forwarding steps from the manual linked above. Create 5 entries; one for each of the ports. Make them match your LAN computers IP's. So if your LAN computer 192.168.0.50 (or whatever) is changed to port 3390 then set up your port forwarding on the Netgear so 3390 goes to 192.168.0.50.
A couple other considerations... make sure your public IP is static or you're using dynamic DNS. Make sure your LAN computers have static IP's. Make sure your LAN computers are set to not sleep or go into standby. That'll kill the network connection.

Now, you're probably going to have problems with the 5 computers. If you have 5 computers listening on port 3389 and all 5 are behind a single public IP then it's not going to work. Well, 1 of the 5 will work. You can port forward to a single IP on the LAN for that port. You either need multiple public IP's or you need to have the 5 computers all listening on different ports.
