How to play Minecraft via Hamachi?
You both put Hamachi with vpn.net, the host creates a network, a friend connects to it using its ID and password. The owner opens up the world for the local network, and a friend goes to the Network Game at the owner's address in Hamachi and the port of chat.
How many people can Hamachi use for free?
Up to five computers in the same network with the owner. More is a pay rate or a Radmin VPN, which has no limit.
Why can't my friend log in through Hamachi?
Most often, a friend doesn't have a license: the open world checks every player at Mojang. Other reasons are different versions of the game, the firewall that doesn't let Java in, and the address isn't from Hamachi.
