Hamachi is a utility created to connect several computers in one 'virtual net' whose characteristics are the same to the ones in a local net

Differently from a LAN, this virtual net is out of reach of routers and firewalls, it avoids configurations others than the ones from Hamachi.

In this way you will have computers from work connected to the ones at home, you may transfer files and synchronize all kind of data.

Hamachi is ideal to establish connections for net games with no need to have the computers in the same local area.
