Cannot connect to Windows 7 remote desktop from WAN but LAN

August 12, 2012 at 12:15:51
Specs: Windows 7, AMD2600/512
Here is the problem,

I have two laptops both are running Windows 7 Enterprise and I cannot connect to its Remote Desktop through the internet (123.234.234.234:3389)

I have made sure of the following already.

1. Remote Desktop was enabled.
2. Allowed connections from any version of Remote Desktop.
3. Allowed Remote Desktop Connection in Windows 7 firewall, both private and public.
4. I am the sole user and hence was an allowed remote desktop user.
5. All services related to Remote Desktop were up and running.
6. I have forwarded port 3389 to the internal IP (i.e. 192.168.1.101).
7. I can telnet my external IP alone but not with the port 3389 along the IP.

The strange thing was I can connect to each laptop's Remote Desktop from within the LAN network by using its internal IP (i.e. 192.168.1.101).

So, what seems to be the problem here and I hope someone can help me to resolve the issue here.

Thanks in advance.

Did you do an online port scan to check, whether the port is show as open for the internet?

Yes, the port 3389 is open, not stealth.

Did you get any error message?
Have you checked the Event Logs for any hint?

Ok, if you're actually adding 3389 to the IP address in RDP, try it without that added on. Which is to say, when attempting a remote connection using RDP, put only the external IP in the box in RDC connection window.

Your port forward will know that it's on 3389 and forward it. It could be adding the port number is confusing your router and it's refusing the connection.

Of course I did not put 3389 along with the IP when attempted the remote desktop connection. .. -_-'

Hard to know that when your initial post showed:

I have two laptops both are running Windows 7 Enterprise and I cannot connect to its Remote Desktop through the internet (123.234.234.234:3389)

All things considered, I'd suspect you have the port forward incorrectly configured.

Sorry for the confusion.

I checked the port forwarding setting but I have no idea what could go wrong.

TCP was set.
Port was correct.
And forwarding IP was right. 192.168.1.101.

You might be right about the port is not properly forwarded.

Here's what I would do if it were me....

1) Ensure you have the most up-to-date firmware on your router
2) Recycle the power on the router (ie: shut it off for 10 seconds, power it back up)

Then try your remote connection again. If it still doesn't work, I would then delete the existing port forward and I would reboot the router and then reconfigure the forward again and try it then.
