VPN and Remote Access Setup

8.1 Introduction

A Virtual Private Network (VPN) is the extension of a private network that
encompasses links across shared or public networks like the Internet. A
VPN enables you to send data between two computers across a shared or
public network in a manner that emulates the properties of a point-to-point
private link.
There are two types of VPN connections: the remote dial-in access VPN
connection and the LAN-to-LAN VPN connection. The "Remote Dial-In
Access" facility allows a remote access node, a NAT router or a single user
computer, to dial into a VPN router through the Internet to access the
network resources of the remote network. The "LAN-to-LAN Access" facility
provides a solution to connect two independent LANs for mutual sharing of
network resources. For example, the head office network can access the
branch office network, and vice versa.
The VPN technology employed in the Vigor routers supports
Internet-industry standard to provide customers with interoperable VPN
solutions, such as Internet Protocol Security (IPSec), Layer 2 Tunneling
Protocol (L2TP), and Point-to-Point Tunneling Protocol (PPTP).
This chapter explains the capabilities of the VPN facility and the remote
access on the router. Use the following setup links on the Setup Main Menu
