Hamachi

A small program designed to create a direct connection between two computers over the Internet. It uses the UDP protocol to establish a virtual private network (VPN). With this program, you can set up a local network between two or more computers. Within such a network, you can perform all the same operations as on a regular network, including file sharing, playing games, running web or FTP servers, and more. The application features an extremely simple and intuitive interface, making network setup easy and straightforward. In the free version, there is a limit on the number of connected devices, up to five.
