VPN Connection pass through to another server PPTP

    Question

  • Hi Guys,
    Here’s a question that will get you thinking! I have the following situation: I have two Academies that need to be connected using a VPN. Academy 1 has a TMG Server which NATS from the SWGFL IP Range to our internal range which is much bigger than the SWGFL Provided range. Academy 2, has a RRAS Server and has a small number of computers with a DNS and DHCP Server.
    I need these two Academy to connect to each other. We have decided to use RRAS to join Academy 2 to Academy 1 using PPTP. I have configured the TMG Server at Academy 1 to allow PPTP Through to the RRAS Server (172.16.0.26) and configured a On Demand interface. When I try to connect from Academy 2 I get the following error (see screen capture).

    Does anyone have any idea as to what is going wrong or how I can setup the RRAS server on the Legacy (SWGFL) network and connect to our internal network.
    Academy 1 setup
    TMG Server 10.3.128.69 (SWGFL Netowrk)
    10.3.128.2 NAT to 172.16.0.26 (PPTP)
    Internal Network
    IP Range Start: 172.16.0.1
    IP Range End: 172.16.65.254
    Academy 2
    RRAS Server: 172.16.100.1 (Default Gateway)
    DHCP Server: 172.16.100.8
    Network Range: 172.16.100.1 – 172.16.101.254
    Hope this makes sense to you I can provide more details if required to assist with this issue.
    Kind Regards
