To understand how this technology works, let's look at how it is used in private organizations. For example, we have a company with 4 offices located in different parts of the country. They will use the Internet to connect them to the same office network. Through the global network, all offices are combined into a virtual local network, and all traffic is fully encrypted as security.
Best free VPN for your computer without restrictions and registration
In our case, to access a blocked site, the user connects to a network, computer, or server over the Internet through a special encrypted PPP tunnel. In this case, data is both encrypted and compressed to speed up transmission.
When connecting to a VPN server, the client must go through three stages: identification, authentication, and then the server authorizes the user and gives him access to certain functions. In particular, we sort of go through it to blocked sites. And since this is a virtual local network, we get a completely new IP address, which is given to us by the Central server. All requests to the server are fully encrypted and are not understood by providers, hackers, or special services when intercepted.
Opera has built-in vpn but it does not work. I use the Google Chrome browser and installed the vpn application in it. Now I can go to sites that are blocked in my country, I just change the country and the ip address changes and everything works. And I don’t need to go through the TOR browser which is very slow. I don’t know what kind of vpn I installed, yes and it doesn’t matter, it works and makes me comfortable.
VPN is considered one of the secure channels for connecting your device to the Internet and also one of the best ways to protect your data from access to them. However, if you have no idea what the privacy policy of a particular VPN provider is or if you do not install and configure the VPN correctly, there is a risk of more security risks than benefits.
To understand the answer to this question, you need to know some concepts and terminology. A connection to a 中国VPN, for example, is called a "tunnel". It is created on the basis of a normal connection to the global network (actually on top of it). A tunnel is a direct connection between your laptop or PC and the server computer, where data is transmitted in encrypted form. By the way, both of these devices are called nodes. In the future, information is sent to external services-sites that you want to open, and your IP address is replaced with a server address.

You should not use a proxy for a browser or extension that promises you online access to VPN: in China this does not work and in most cases you will at least be left without communication at all and without the ability to download another program.
There are almost no public Wi-Fi networks in China in hotels and cafes in restaurants. But at open points, communication is very slow. Pages load in minutes and not always completely. According to tourists' reviews, it is most reliable to use mobile Internet, most operators offer 4G Internet and 3G Internet.
