Sorry for my English, let me elucidate you by examples:
Let's say I'm in Germany and my friend in France. I host a network for a game and my friend joins the network. now how does our data travels through the net?
1. Does it directly goes from Germany to France, without going trough any server?
Or
2. Data starts moving from Germany Goes to the Hamachi servers wich for example are located in Spain, and then goes to the France?
In games, ping is a important factor and the shorter the distance, better the ping. If from the examples above the second one is correct, then where does the hamachi server is located at?
If none one them are correct, please care to explain me how does hamachi works in a simple manner.
