You can configure two types of connections: a connection to the Internet through your ISP and a tunnel connection to the PPTP server on the target network. Depending on how you will be using PPTP, you may not need to configure both types of connections.
PPTP is most commonly used for enabling secure and encrypted communications to private enterprise networks using a serial (modem) or ISDN connection to the Internet. In this scenario, you must configure both connections: one connection to the Internet through an ISP and one tunnel connection through the Internet to the PPTP server on the target network.
However, if you are using PPTP to connect to a PPTP tunnel server on your LAN, you only need to configure a connection to the tunnel server.
The following procedures describe how to use Dial-Up Networking to configure ISP and PPTP connections.
