A VPN overview.

Before setting up this VPN server, it is necessary to understand some of the relevant knowledge, because the use of VPN services requires a certain network base. A VPN (virtual private network) is a virtualized private network, which is a secure tunnel formed through the Internet by two devices (computers or firewalls) with VPN-initiating connectivity. At the initiator of the tunnel (i.e. the service side), the user's private data is transmitted over the Internet after encapsulation and encryption, to the receiving end of the tunnel (i.e. the client), and the received data is securely reached to the user end after it has been unpacked and decrypted. It is self-evident that this approach can securely transmit private data on an unsecured internet to enable internet-based networking operations. The effect of VPN technology is similar to the traditional DDN line networking, the network topology is shown in the following figure.
