The main two things that VPN does are:
Spoofing an IP address with a fake one - VPN changes your IP address to a machine address from another country. Your real address is hidden behind a new IP, you can visit sites without fear of restricting access from various resources.
Connection encryption - without a VPN, access to resources goes through the provider. Using a VPN, data passes through the service over an encrypted channel, hiding access to the real IP address

It is on these two pillars that his work rests. By connecting to the country offered from the list, you start surfing the Internet as if being in the country you have chosen. At the same time, your connection goes through an encrypted channel - neither your provider nor the system administrator has access to your browsing history.

VPN is developing very quickly and is already used by millions of users around the world. There are always a lot of services on the Internet that provide such services.

But despite its popularity and rapid development, many do not know what this technology is and what it is all about. You can find out more about this by reading this material.

Often, the enterprise network consists of several segments with different levels of security and trust. In this case, you can use a VPN to interact between segments, which is a much safer solution than simply joining networks. For example, this way you can organize the warehouse network's access to individual resources in the sales Department's network. Since this is a separate logical network, you can set all the necessary security requirements for it without affecting the operation of individual networks.

As clients of the VPN server with a high probability will be workstations running Windows, while the server can work under Windows, Linux or BSD, so we will consider the connection settings on the example of Windows 7.We will not stop at the basic settings, they are simple and clear, we will Focus on one subtle point.

When connecting a normal VPN connection, the main gateway will be specified for the VPN network, meaning the Internet on the client machine will disappear or be used through a connection in a remote network. It is clear that this is at least inconvenient, and in some cases can lead to double payment for traffic (once in a remote network, the second time in the provider's network). To exclude this point, on the Network tab in the properties of the TCP/IPv4 Protocol, click the Advanced button and in the window that opens, uncheck Use the main gateway in the remote network.

So, a virtual private network PC 免费梯子 is a technology that provides a secure (closed from external access) connection of a logical network over a private or public network with high-speed Internet.

This network connection of computers (geographically separated by a considerable distance) uses a point - to-point connection (in other words, "computer-to-computer").

Scientifically, this connection method is called a vpn tunnel (or tunnel Protocol). You can connect to such a tunnel if you have a computer with any operating system that has a VPN client integrated into it, which is able to "route" virtual ports using the TCP/IP Protocol to another network.
