How to setup a VPN Connection in Windows 7

VPN (Virtual Packets Network) is a service meant for establishing a secured communication between a remote user and server by accessing the public network like the internet. This will enable user to access the documents shared on the network. These documents include text documents, music, audio, videos. You also have privileges to make your Windows 2000 sever-based computer a remote-access server so that other users can connect to it VPN and get access to the data available on your local drives and network folders. Virtual private networks accomplish this by “tunneling” through the internet or other public network via authenticated links which offers secured communication between the concerned devices. The components of a VPN:rn1. VPN server: It is responsible for controlling and regulating the secured data transmission between the user and computer network.rn2. VPN client: The user which send request to establish a dynamic connection between client and server.rn3. VPN connection: The portion of the connection in which data is encrypted by highly secured algorithms which can’t be traced by any hacker.rn4. Tunnel: The portion of the connection in which data is encapsulated while the data transmission occurs.rnVPN highly secured encryption algorithms which ensure proper security and the information can’t be intercepted by any unauthorized person/ hackers. For ensuring the security two types of protocols are used which are as follows: • Point-to-Point Tunneling protocol (PPTP): This protocol is responsible for data encryption while data transmission in VPN network. • Layer Two Tunneling Protocol (L2TP): This protocol is responsible for data encryption, authentication and integrity using IPSec.rnSteps for How to install and enable VPN:rnBefore establishing a VPN connection between the two computer, firstly make sure that both the computers are connected to the internet through LAN (Local Area Network) or WAN (Wide Area Network)If connected then follow the steps mentioned below: 1.
