Hamachi server?

[SweetSnowEcho]

Hello everyonge, so a friend of mine wanted to play on a hexxit server with me and i was looking into how to make one and came across hamachi. Well now i have a prolem. What's the difference between managed and unmanaged? Do you have to play for one of them? If you get the free one what limitations do you face? How many servers could I make with the free one? and other things, if someone could help me with that, it would be great thank you
