Unable to Get Port 3389 Open and “Seen” for Remote Desktop (from iPad over Fios Router to XP Laptop)
I am working to get remote access to my corporate laptop from my iPad using remote desktop.
• Laptop – Running Windows XP SP3, my corporate IT folks have turned on Remote Desktop.
• Router – My home network has a Fios Actiontec MI424-WR (revE) router, and I have turned on port forwarding for 3389, pointing to the IP address of my laptop on the home network (192.168.x.x).
• iPad – The iPad is running Mocha Remote Desktop (RDP), where the configuration requires only the IP and port; I have configured with the external IP address for my router, and port 3389.
I am able to connect with remote desktop when the iPad and laptop are both on my local network at home. But when the iPad is on an external network, it fails to connect and times out.
I have tried setting up Dynamic DNS on the router (created a DynDNS account, entered the xxx.dyndns.org host name in the router settings, and tried pointing the iPad’s remote desktop app to xx.dyndns.org) but this also failed to connect and timed out.
(I can not try Remote Desktop with another port, as I can not make admin changes to the corporate issued laptop.)
Here are some of the rudimentary diagnostics I have checked:
• Listening – When I run ‘netstat –a’ from the laptop, it shows that the machine is listening to port 3389.
• CanYouSeeMe – When I test for port 3389 using CanYouSeeMe.org on the laptop, it reports that it can not see my service on Port 3389.
Why would port 3389 show as forwarded on the router settings, be show as listening from the laptop with netstat –a, but not be “seen” with port testing? What am I missing to be able to connect from outside of my own network?
