  • Windows 2003 PPTP/VPN and windows 7 clients

    Hi,

    I have setup a PPTP VPN service on windows 2003 R2.

    Clients are given a IP via DHCP

    XP clients can connect fine and are assigned a IP in the form off

    IP: 169.254.43.37
    Subnet mask: 255.255.255.255
    Gateway: 169.254.43.37

    Windows 7 clients connecting get similar IPs except I noticed the default gateway is empty and set to 0.0.0.0

    I've also tried connecting using a mac and it works fine with no issues.

    any help would be really appreciated.

    What is the question? Do the Windows 7 machines not get a connection?
    1 1 was a racehorse.
    2 2 was 1 2.
    1 1 1 1 race 1 day,
    2 2 1 1 2

      Are you deliberately assigning addresses in the APIPA range?

        How is your client IP addressing handled by the PPTP server? Did you specify a range or is it supposed to grab from a DHCP server on the LAN?

          Is the gateway set to zero's or is it empty? Does this apply to the VPN adaptor only or to the local connection too?

          There is an issue where the gateway can be removed each time a Vista PC is rebooted, but I'm not sure if this also affects Win7. It is also possible to ignore the gateway settings obtained from the DHCP server by configuring it on the settings of the VPN adaptor's TCP/IP properties>Advanced>DNS settings. However, what this looks like when you IPCONFIG /ALL I don't know... presumably the adaptor would then take the local connection's gateway details.

            it looks to me like there is an issue with the way dynamic addresses are being assigned, and the Win7 hosts are probably just not ending up with an apipa address.


            Also - review the following link, and see if PPtP is really the best solution for your environment....
