8.4.3  PPTP Encapsulation
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure 
transfer of data from a remote client to a private server, creating a Virtual Private 
Network (VPN) using TCP/IP-based networks.
PPTP supports on-demand, multi-protocol and virtual private networking over 
public networks, such as the Internet.
