WinXP system establishes a VPN connection virtual private network connection

WinXP system VPN connection, also known as virtual private network connection, can effectively help you prevent computer data from being stolen and extend your private network. Nowadays, the network is developing more and more rapidly, and the VPN technology has become more useful. The following is a small series to explain the VPN connection and the method of creating a VPN connection.

VPN (Virtual Private Network), translated into Chinese as a virtual private network, using VPN technology, users can remotely access an internal network (such as a corporate LAN) through the Internet, after authentication, even if In fact, the user is at the other end of the globe and can access the network as if he were accessing local network resources. At the same time, because it uses a special encryption technology, it can ensure that the data in the internal network is not stolen by other users on the Internet.

VPNs use a technology called tunneling to securely transfer data over the Internet to remote access servers on your workplace network. When using a VPN, it is possible to save money by using a public Internet instead of making long-distance telephone calls when making a secure connection to a private network. In addition, because the VPN encrypts the Internet connection, it is also very secure. The new authentication and encryption protocols are enforced by remote access servers. Sensitive data transmitted over the Internet is private to the public, while legitimate users can securely access these confidential data over VPN.

Paths to Create VPN Connections

There are two ways to create a VPN connection: dial-up with an Internet Service Provider (ISP) or connect directly to the Internet.

If you are dialing into an ISP, your ISP will then call the remote access server of the private network to establish a PPTP or L2TP tunnel. Once the authentication is complete, you can access the private network.

If you are connected to an Internet LAN, cable modem or digital subscriber line (DSL), you can tunnel through the Internet and connect directly to the remote access server. Once authenticated, you can access the company. The internet.

Through the above detailed introduction, I believe that everyone knows the VPN connection under WinXP and its creation path, you can use VPN to do a lot of things, give full play to its effectiveness and role.
