How to create VPN connection(Windows)

Windows 7
In this article we will learn how to configure a connection to a virtual private network (VPN) using Windows 7. This article will show you how to create a new VPN connection using Microsoft Windows 7. By creating an encryption tunnel through the Internet, data can be passed safely

What is APN.
A VPN is a private network created over a public one. It’s done with encryption, this way, your data is encapsulated and secure in transit – this creates the ‘virtual’ tunnel. A VPN is a method of connecting to a private network by a public network like the Internet. An internet connection in a company is common. An Internet connection in a Home is common too. With both of these, you could create an encrypted tunnel between them and pass traffic, safely - securely. 

If you want to create a VPN connection you will have to use encryption to make sure that others cannot intercept the data in transit while traversing the Internet. Windows 7 provides a certain level of security by using Point-to-Point Tunneling Protocol (PPTP) or Layer Two Tunneling Protocol (L2TP). They are both considered tunneling protocols – simply because they create that virtual tunnel just discussed, by applying encryption.

Configuration.
If you want to configure a VPN connection from a Windows XP client computer you only need what comes with the Operating System itself, it's all built right in. To set up a connection to a VPN, do the following:

1.Open up network and sharing center from Control Panel, and choose Set up a new connection or network.

2.There are two options in the Connect to a Workplace window. 99% of the time you just need to pick the first option, unless your company only allows you to dial in using a phone line.

3.Type in the address in either domain name or IP address, and name the connection in the destination name box. And click Next.

4.You can leave all user login info blank if you feel safe that way in the next window. And clickCreate. You’re all set if you see the next window as below.

5.To launch it, simply click the small network icon on the system tray at the bottom right corner, and pick the connection we just created from the popup list, and connect.

6.Type in your user name and password, and you are on your way connecting your Windows 7 to your company network.
