Hamachi is a desktop tool to create and manage a VPN (virtual private network) between multiple remote computers. You can also simulate a fully encrypted and secure local network, which can be very useful for some games.
Developed by LogMeIn Inc., Hamachi provides you with the capability to establish direct links between computers that are behind network address translation (NAT) firewalls without any reconfiguration needed. This software solution is available to be downloaded and used free of charge for up to 5 computers on your Windows system. Alternatively, you can check out other VPN programs like NordVPN or ExpressVPN.
