set up a PPTP VPN server

    Question

  • Has anyone figured out how to create an incoming connection for a PPTP VPN server? I know in XP and Vista it was a piece of cake, like 10 clicks. But I cannot for the life of me figure out how to do it in Windows 7. I can create a connection to a VPN, but I cannot create my own VPN server to recieve incoming connections.

     Any help would be appreciated!

  • Many people using this solution however, this type of setup does not allow client computer to share the internet connection with the VPN server, when the client connect to the host so-called VPN server, the clients system no longer has the browsing capability.

    Can anyone tell me how can you setup a "real" VPN server that allow the client share the vpn server's internet connection? Just like some commercial paid version that you can use their VPN service as VPN Proxy-like.

  • I am not sure I understand the problem. But let me try it. You can check "Use default gateway on Remote Network" on the VPN client to access via the VPN connection. However, for security reason, some companies may disable this feature. This link maore help too.

  • This was helpful.  I tried connecting from my PC after creating this connection on my fathers.  I still cannot connect.  I'm using his public IP which displays using any "What's my IP" site.

  • What's the VPN error code? Make sure the VPN port 1723 is open by using telnet to test it.

  • If I telnet from my remote pc to his Public IP address which is then forwarded to the "VPN Server" using port 1723 it seems to connect.  If I try using Windows to connect via PPTP I get the following error.  Just FYI I have port 1723 and 47 forward to my father's PC which is the vpn server.  Windows firewall is disabled.

  • I did another test on my remote PC using pptpclnt.exe and here's what I got:

    Initializing WinSock...
    Obtaining host information...

    ======================================
    Enter data to send to server (between 1 and 255 chrs.), then hit ent

    Waiting for a reply to the data which was just sent...

  • Thank you for the detail information. In most cases, the VPN error 806 GRE issue. Here are some sugegstions.

    1. If the router is PPTP passthrough, you don't need to forward port 47 because GRE uses IP protocol 47 not TCP port 47.

    2. Make sure you don't enable DMZ on the router.

    3. It could be the security software block the VPN. Try clean boot.

    4. If you are uing wireless, try to use wired for a test.

  • The problem ended up being that the GRE was being forwarded as a port instead of as the protocol.  Once we fixed this the VPN worked flawlessly!

    So how we go it to work.

    1. Setup VPN access on PC

    2. Setup port forwarding to route PPTP to "VPN Server" mention in step 1.

    3. Forwarded GRE to "VPN Server".

    4. Accessed VPN from remote PC using the Connect to Workgroup option on Windows 7 PC.

    Thank you!
