Basically what you need is a LAN Network program..
The main programs i think is
I'm not too sure on how to use these but you can get access in using a extra Local Area Connection newtwork by which you can access LAN in different types of countries
So i don't quite remember on how hamachi is used... so maybe if you can watch the tutorial..
And Tunngle is pretty sure i remember my big brother used it last time..
In order to use these you must register on their website
choose any one you want..
If you login in Tunngle you can search any games that has multiplayer
and it will show you every tip on how to use it and what errors you can solve if you play(In a game)
Soo my big brother haven't tried minecraft so i hope you can understand on how to use it
