NBG-318S User’s Guide

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.
This screen displays when you select PPTP encapsulation.
