PPTP Point-to-Point Tunneling.

A protocol for use with remote access which carries encrypted, secure traffic over the Internet between an Internet service provider (ISP) and a remote access server. It requires the use of the Point-to-Point Protocol (PPP) between the remote client and the ISP and provides substantial savings versus telephone calls between the client and the remote access server using regular long distance or 800 number service. (See remote access, encryption, Internet service provider, server, and Point-to-Point Protocol in the hard copy dictionary.)
