Tp-Link TL-ER604W V1 [2/64] Vpn overview

1. VPN Overview

VPN (Virtual Private Network) is a private network established via the public network,

generally via the Internet. However, the private network is a logical network without any

physical network lines, so it is called Virtual Private Network.

With the wide application of the Internet, more and more data are needed to be shared

through the Internet. Connecting the local network to the Internet directly, though can allow

the data exchange, will cause the private data to be exposed to all the users on the Internet.

The VPN (Virtual Private Network) technology is developed and used to establish the private

network through the public network, which can guarantee a secured data exchange.

VPN adopts the tunneling technology to establish a private connection between two

endpoints. It is a connection secured by encrypting the data and using point-to-point

authentication. As the packets are encapsulated and de-encapsulated in the Router, the

tunneling topology implemented by encapsulating packets is transparent to users.

The tunneling protocols supported by TP-LINK Routers are as below:
