How China VPN works
It's a bit difficult to describe how a VPN works, unless it's a small technical detail. However, for those who need a basic concept, a VPN creates a secure tunnel from your device to the VPN server and then from there to the Internet.
In detail, the VPN first installs the communication Protocol on the device. This Protocol sets restrictions on data transfer from your device to the VPN server. There are several basic VPN protocols that are common, although each has its own advantages and disadvantages.
Shared VPN Protocol
Although there are many communication protocols, there are also some basic programs that are generally accepted, regardless of the brand of VPN service. Some are faster, some are slower, some are safer, and others are smaller. Your choice is based on your requirements, so this section is worth paying attention to if you plan to use a VPN.
In conclusion -
OpenVPN : the Medium-speed open source Protocol still offers strong encryption support.
L2TP / IPSec : this is also quite common and offers decent speeds, but is easily blocked by some sites that do not support VPN users.
SSTP : This is not widely available and, apart from good encryption, not much to recommend.
IKEv2: very fast and especially good connection for mobile devices, although it offers lower encryption standards.
PPTP : Very fast, but over the years it has been filled with security gaps.
Corporate VPNs are typically used to remotely access employees to internal company resources through an encrypted connection. VPN in this case serves to ensure that employees located on different networks can work inside the same virtual network after connecting. Home users use these technologies in a slightly different way. Remote access is used to hide the location of your computer and access limited resources. For example, a popular music service is restricted to access from. With a VPN connection, this resource will be “unlocked”.
Each peer is responsible for encrypting the data before it enters the tunnel, and this data will be decrypted after it leaves the tunnel. After connecting to the VPN server, all data begins to be transmitted between your PC and the server in encrypted form. Already from the VPN server, all data is transferred to the external resources that you request. Here is a beautiful picture that clearly demonstrates all the "magic":
Among the methods of protecting and anonymizing traffic available to most people, VPN services seem to me the most optimal option. VPNs offer faster connection speeds and higher levels of protection than Tor, Proxy, or anonymizers. However, most VPN providers are paid, which means you have to spend money. What ultimately to choose is up to you.
Most VPN services provide the opportunity to test quality for free over a short period. Testing period can be from several hours to several days. During testing, you usually get full access to all the functionality of the VPN service. Our service makes it possible to find such VPN services at the vpn免費windows stands for Virtual Private Network, which means Virtual Private Network. A VPN is created on top of an existing network, such as a regular local area network or the Internet, and can combine computers in different parts of the world into one logical network.
