Cannot DRP to Windows 7 via router port forwarding

Hi,
I have setup a port forwarding rule in a clients router to to connect to a laptop on the LAN from the outside via RDP. They can RDP locally but it failes if trying from outside the LAN. Other pcs work OK with same setup.
Is there any trick with Win7?

Thanks

what version of RDP are you connecting FROM? if XP you will need the 7 box to accept connections from any version of Remote Desktop
RDP is turned off by default on Windows 7.  Start > Right Click Computer > Properties.  Click the Remote Settings in the left pane.  Under Remote Desktop, make sure the first option, "Don't allow connections to this computer" is not checked.
Hi CompTroub,

Make sure that the "Allow connections from computers running any version of Remote Desktop (less secure)" is selected on the System Properties > Remote tab. See attached.

Other than that, Windows 7 uses the same port (3389) by default to facilitate RDP connectivity. Check HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\PortNumber in the registry to be sure.

Let me know if this helps?  :)

Hi Guys,

As I mentioned in quesion we CAN connect within the LAN so that bits you are mentoning above are all good:)

Thanks
Oops ... I misinterpreted your original post. Apologies!

1) If everything is working okay on the LAN but not WAN, what have you done to rule out connectivity issues (of the logical/software variety, since we know the hardware is likely not the culprit based on other machines working as intended)?

2) Have you tried PrtQry (http://www.microsoft.com/downloads/details.aspx?familyid=89811747-c74b-4638-a2d5-ac828bdc6983&displaylang=en) or a similar port scanner (https://www.grc.com/x/ne.dll?bh0bkyd2) to ensure that your port forward successfully reaches the Win7 target from an external/WAN source?

3) If using Windows Firewall, temporarily disable it using:
netsh advfirewall set currentprofile state off
(To turn it back on, use netsh advfirewall set currentprofile state on)

4) Any specific error messages, or just timeouts?

Thanks for providing further clarification ... hang in there!
