    VPN Connected but no network access; TCP/IP Not connected


    I'm having problems getting a VPN to work which seems to be a common problem but I cannot find a solution

    Basic hardware:
    XP and 2 win7 Ultimate computers (A&B). B is the VPN server.
    Router: Thomson SpeedTouch TG585v7Xp . Port Forward tester confirms port 1723 is open
    Internet access via Router or via local wireless hotspot (FON)

    I have followed the tutorials on this site https://www.sevenforums.com/tutorials...nnections.html to set up the VPN at both ends (so I have a special VPN user set up)

    If XP is logged onto the LAN, it will connect (shows connected at both ends) to the VPN using the LAN IP address (192.168.etc) I'm not sure what use this is as I can see the shares on B through the network anyway!! The VPN connection does not show up anywhere else.

    Also rather oddly, if I click on the workgroup name in Explorer I am told the workgroup is not accessible (not have permission etc etc) despite the fact that I can see and access the other two computers in the workgroup

    I copied the VPN connection, changed the IP address to the external address of my router (188.222 etc)
    Logged the XP machine onto the local Wifi hotspot (109.144.etc) and connected again (VPN connections show connected on both computers) no problem

    The server connection is valid only for the VPNuser and as all bar TCP/iPv6 ticked.
    TCP/iPv4 has
    * Allow callers to access my network ticked
    * Assign IP address automatically
    * Allow caller to specify its own IP address

    The VPN user also shows in network Connections but IP/v4 shows not connected. (Details tab is blank) and 'Diagnose couldn't identify the problem

    I've cancelled all firewalls and AV software on both machines and I've repeated the process using the wireless connection to my router but it makes no difference.

    Form the various posts on this subject, I have also
    * unticked use default gateway on remote network. No change
    * ensured there is a shared folder (shared for the VPN user and everyone)

    And now I'm going to beat the sh1t out of a cardboard box!!

    Any suggestions welcomed

    hi
    i am sure i can help you but i need you to answer some questions first
    are a & b on the same router
    when you config the server you have to change :Assign IP address automatically: and set ip address pool anyway as you are using normal windows not server so you cant have more than one client connected at the same time
    also another tip you have to change the router server to be uncommon ip address like 192.168.xx.xx
    try to keep Assign IP address automatically on the client first then try with out
    try to map the drive using ip address \\xxx.xxx.xx.xx\(shared local disk) example d
    try to map it Assign IP address automatically is on and off
    let us know if they are on the same router or not as it does make difference

    Do you have ICS enabled?

    I believe you have to have ICS enabled in order to have a connection while using a VPN.

    ICS and VPN connections

    If you create a virtual private network (VPN) connection on your host computer to a corporate network and then enable ICS on that connection, all Internet traffic is routed to the corporate network and all of the computers on your home network can access the corporate network. If you don't enable ICS on the VPN connection, other computers will not have access to the Internet or corporate network while the VPN connection is active on the host computer.

    Hi All
    Sorry I've not replied to your suggestions but its been a bit hectic. MY ISP has made some major changes; I've had work problems and so on. Anyway, not much has changed!!

    Rather than try to remember where I had got to I
    * Deleted all VPN connections. Rebooted both machines (XP, Win7)
    * Created both VPN connections
    - Incoming on Win7. Port 1723 forwarded in router to m/c with incoming connection. Firewall off. Internet connected. ICS enabled (other computers on this network can access the internet)
    - Outgoing on XP. Told to connect to External IP of router of network on which Win7 sits. Internet connected.
    * Activated outgoing VPN which connects OK (Outgoing and incoming connections both show connected)
    However, incoming VPN shows username connected to WAN but IPv4 and IPv6 not connected.

    Answering the rest of the questions
    * Win7 is on a network with another PC both connected to the router
    * XP is not on a network and is connected to the internet wirelessly
    * Server is 'Assign IP automatically using DCHP'
    * Router network works just fine so I presume IP addresses are OK
    * Client VPN Assign IP is automatic


    I then changed Client VPN Assign IP to use the following IP (not one in use elsewhere in the network) and the connection stuck (error 721) on verify username and password (but I hadn't noticed I need to enter a DNS IP address as well)

    Oh and I tired unticking use remote gateway - made no difference.

    So there we have it - VPN connected but no IP connection

    Any further thoughs?
