I am trying to activate PPTP access through an ISA server to another company's server. I have 2 current IP Packet Filters for allow PPTP (VPN filtering to allow PPTP packets on client and server side. Filter type is PPTP CALL for client, and PPTP RECEIVE for server. Protocol 47, direction both. On the VPN settings, the Networking Tab setting is "Type of VPN server I am calling" is set to Point to Point Tunneling Protocol (PPTP). It starts connecting to the address, and then after 30 seconds, I get the following message: Error 678: There was no answer. The IP address is correct. I am assuming that my IP Filters (in ISA) are not set correctly. Any ideas for this novice? Thanks
