6.3.3 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.
The screen shown next is for PPTP encapsulation.
