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 internetwork 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 first, “Remote Dial-In Access” means the router

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

second, “LAN-to-LAN Access”, 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.

Draytek Vigor router’s virtual private networking (VPN) supports Internet-industry standards

technology to provide customers with open interoperable VPN solutions such as Internet

Protocol Security (IPSec) and Layer 2 Tunneling Protocol (L2TP) as well as Point-to-Point

Tunneling Protocol (PPTP).
