Windows 8 Pro Remote Desktop issue

    I have a weird issue here.

    I'm running Windows 8 Pro. The client computer is also running Windows 8 Pro. Remote Desktop works when I'm in the same network.

    I tried connecting using my external IP Address and my DynDNS account, neither works. I disabled Windows Firewall and setup DMZ for my computer on the router, still can't get remote desktop to work.

    I verified www.canyouseeme.org, port 3389 is open, which is obvious since I'm running DMZ! My ISP, Bell Canada (modem/router: Sagemcom F@st 2864), blocks port 80 and 25, but I don't need those for RDP, do I?

    The funny thing is RDP rejects the connection instantaneously for my IP or DynDNS while it takes a while for another address.

    Thank you, Michael

    I found the issue.

    I am not sure if this is my network configuration or a normal thing but I cannot connect using my external IP when I'm at home, it works fine at another location.

    I'm trying to set up my computer so I can remote access it from anywhere including outside the local network.

    I have it working locally by following this tutorial but it was old in XP era. But now I'm using Windows 7.

    What I'm doing wrong here? Or am I missing something?

    What I have tried so far:

    I know I need to forward the RDP port to 3389 on the router, but I'm not so sure if I'm doing it right. But here is what I did:

    1. I went to http://www.dyndns.com/ and get myself a domain name
    2. I download the DynDNS updater on my host computer so I can use the DNS rather than my IP address (I can ping my newly registered xxxx.selfip.com so I assuming I got that right)

    3. I went to my router admin page setup the port forwarding table to 3389 with my private IP address like this:

      D-Link Air G Plus Advanced options screen

    All the remote desktop services are running and it works fine in my local network

    But I when I try to connect I get the error:

    Remote Desktop Errors

    As the remote desktop is working internally, the problem must be between the computer and router.

    First I would test the port is open using Can You See Me or telnet. If you receive no response, then have a look at the routers firewall settings, it maybe blocking the incoming connection.

    One other possibility is your ISP maybe blocking port 3389.

    If you are trying to use the xxxx.selfip.net from the LAN side of the router, many routers can't resolve the WAN Side of the router from inside the LAN. It's like picking up the phone and dialing your own phone number. Try using a friend or family members computer to remote connect and see if it works from outside.

    Have you checked the firewall on the Windows 7 computer to make sure it allows remote connections from the internet. On my computer I have three profiles for connections when setting up the firewall: Domain, Private and Public. If the port is not open for the Public profile, that may explain the issue.
