This chapter shows you how to configure the Prestige for VPN connection.
7.1 Overview
A VPN (Virtual Private Network) provides secure communications between sites without the
expense of leased site-to-site lines. A secure VPN is a combination of tunneling, encryption,
authentication, access control and auditing technologies/services used to transport traffic over
the Internet or any insecure network that uses the TCP/IP protocol suite for communication.
Your Prestige supports three main types of VPN (Virtual Private Network): PPTP, IPSec and
L2TP.
7.2 PPTP
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. You can set the Prestige to initiate a VPN connection or accept
connection requests from a VPN client.
