I have a new computer with Win 7 Pro at work (on a peer-to peer network, no server) that I need to access with Remote Desktop so that I can work from home and still be with the family. For years I have been using Remote Desktop Connection from my home desktop using Win XP SP3 desktop to my Win XP Pro SP3 desktop computer at work. I am able to connect (locally) from my old work WinXP desktop computer to my new work Win 7 Pro computer. I can connect from home Win XP Pro SP3 computer to work Win XP Pro SP3 Computer through internet (DSL). I can connect from Win 7 computer at work to home WinXP computer through internet (DSL).
I also tried to use remote desktop client from my wife's Win 7 home laptop at home over the internet to access the work desktop Win 7 Pro computer, same problem, unable to connect.
Thus I have the DSL Modem(s) port forwarding setup correctly, IP addresses are correct, compatible Remote Desktop clients. Firewall exceptions are setup correctly.
What is different. The new computer with Win 7 Pro has McAfee Internet Security all others running Kaspersky IS. Win 7 Pro Computer is new. Subnet at home is different than subnet at work (like 192.168.0.x vs 192.168.20.x). Since I am using various connections, listening port has been changed from 3389 on some computers including the new Win7 computer (This should not be a problem as I am able to connect locally).
Disabling firewalls (Anti-Virus/IS software) on both computers does not help. In any case I can go from WinXP Pro at work to Win 7 computer at work locally. New work Win 7 computer has wireless that was automatically setup first and then during setup
added the wired Ethernet connection. At one point I tried disabling Wireless. No joy.
My thought is that there may some security policy or possibly a protocol issue that is different with new Win 7 computer that does not allow a connection outside of the local network (over a public network).
I have also tried to set up a Microsoft built-in VPN connection: Forwarded port 1723, Enabled GRE protocol in DSL modem. Tried all different scenarios between Win XP at home and Win 7 computer at work and cannot set up the VPN connection. I get error 678: The remote computer did not respond.
I have connected from home to old work Win XP computer and through that another connection from the same work Win XP computer to new Win 7 Pro desktop computer. that appears to be the only way that I can access it remotely, but the connection is too slow.
I have reviewed hundreds of help/knowledge base discussions and threads. I have reviewed or followed all the instructions on various tech websites for setting up VPN connections and Remote desktop connections.
Anyone have any idea as to what the solution here might be?
