Appendix: What is VPN

The full name of VPN English is “Virtual Private Network”, which translates to “Virtual Private Network”. Vpn is defined as establishing a temporary, secure connection over a public network (usually the Internet), a secure, stable tunnel through a chaotic public network. Use this tunnel to encrypt data several times to achieve the safe use of the Internet. A virtual private network is an extension of an intranet. Virtual private networks help remote users, corporate branches, business partners, and suppliers establish trusted, secure connections to the company's intranet for secure extranet virtual private networks that connect to business partners and users. VPN mainly uses tunnel technology, encryption and decryption technology, key management technology and user and device identity authentication technology.

Features that VPN can provide: Firewall function, authentication, encryption, tunneling.

VPN can connect to the Internet through a specially encrypted communication protocol, and establish a proprietary communication line between two or more intranets located in different places, just like setting up a dedicated line. But it doesn't really need to lay physical lines like fiber optic cables. This is like going to the telecommunications bureau to apply for a dedicated line, but there is no need to pay for the laying of the line, nor to buy hardware equipment such as routers. VPN technology was originally one of the important technologies of routers. It supports VPN functions in switches, firewall devices or Windows 2000 and above. In a word, the core of VPN is to use the public network to establish a virtual private network.
