Virtual Private Network, or commonly called as VPN in the tech world, is a network that utilizes publicly-available telecommunication systems, like the Internet, to provide offices, companies, and organizations a secure and reliable access to their own network. VPN is like having your own exclusive leased Internet line only that VPN is much cheaper to operate and maintain.
VPN uses Internet protocols, also called tunnels that only allow registered computers in the network to get through. It is like allowing only those who have proper identifications and passwords to enter the tunnel and access information available inside. Using VPN, computer users send and receive encrypted data through a tunnel. This tunnel cannot be accessed by outsiders or anyone who does not have authorized access.
VPN, therefore, protects important corporate data and information that are exchanged through the network. VPN was conceptualized to prevent hackers, outsiders, and business competitors from accessing confidential information on a certain network. Today, network professionals are working on how to further make the VPN secure and reliable and how to encrypt information both sent and received within the network.
How to set up a VPN in Windows XP and Windows 7? There are actually some easy steps that you can follow. Here are some basic steps. Please take note that these steps apply to Windows XP and Windows 7 operating systems only. While these are easy steps to follow, it is still recommended to leave the VPN setup to network professionals to ensure a secure connection is completed.
First, open Control Panel and click on the Network and Internet icon. A list of existing dial-up and LAN connections will appear. When you choose the “Create a new connection” icon, the Windows XP New Connection Wizard will appear on the screen.
Click next to begin the wizard then select the “Connect to the network at my workplace” from the list. Click Next. Choose the “Virtual Private Network connection” option and click next. Fill in the “Company Name” field and click next. Choose an option on the “Public Network” screen and click next. Choose the “Do not dial the initial connection” option.
Enter the IP address of the VPN server to connect to and then proceed by clicking next. If you don’t know your IP address, ask your network administrator. Select an option on the “Connection Availability” screen and then click next. Click finish to complete the setup. There are other ways to setup a VPN using other operating systems. In most companies, users don’t actually have to setup a VPN because network administrators do that for them. If you are running a small office or business, however, you can setup the VPN yourself to save on costs of hiring network professionals.

While the basic VPN network encrypts the flow of information within the office, large companies use VPN to connect to their branches around the world using the Internet. This saves them the expense of long distance telephone calls because people from other branches can easily communicate with the main branch and send important data and information using the VPN.
