How to use PPTP?
To use PPTP, you set up a PPP session between the client and server, typically over the Internet. Once the session is established, you create a second dial-up session that dials through the existing PPP session, using PPTP. The PPTP session tunnels through the existing PPP connection , creating a secure session.
