I have Windows 2000 Server acting as a VPN Router, we have a Cisco 1720 Router with built-in Firewall. I have opened the PPTP,GRE and L2TP ports on the router to allow a secure vpn connection. Using the VPN Setup Wizard I have created plenty of PPTP and L2TP ports in which to access the vpn server using the Routing and Remote Access on Win2k Server. I also have created a connectoid for the client and setup a Certificate server to issue an ipsec certificate to the client so they can create a secure connection. The VPN Server can be seen via a web interface from the internet, so I know it is visible. Yet every attempt to connect with the connectoid fails to make a connection. I am no VPN Guru and I would appreciate any assistance anyonecould provide in creating a VPN connection using PPTP or L2TP to our LAN from the internet.
