    I am having some problem regarding ISA Server 2006.I have configured ISA Server 2006 in my network and i want to establish PPTP VPN connection from Client to the VPN Server which is located on the internet.I successfully connected to the VPN server from my client computer when i was behind the router but i couldn't establish my VPN connection when i was behind ISA Server 2006.Whenever i tried to connect i got 619 error.I also created the access rule in ISA that " Allow All Outbound traffic from internal to external but still got the same problem.I hope someone would help me out in this matter.

    Regards,

    Qaiser Ajaz

      Hi,

      please have a look in the ISA Server realtime monitoring to see if something gets blocked! The client must be a SecureNAT client. The ISA Firewallclient must be deactivated during the VPN connection. Please check also that the PPTP filter is acivated on ISA Server.

          Hi,

          have you checked the PPTP conenction from another internal client? Any error message in the TMG log during the VPN client connection?
          Does this help?
