Last week I was trying to play one of my favorite games Starcraft over Hamachi with some friends. Starcraft is not the newest game, so unlike many newer games it doesn’t give you the option to pick your network interface.
While we were logged into our Hamachi network we were able to ping each other and followed all the troubleshooting instructions given by the Hamachi site. This was despite the fact that starcraft is one of the games that is supposed to “just work” with Hamachi. None of us were able to see games that anyone else created. After tinkering around with this for probably about a half-hour my friend orb360 found a solution. The steps to get Starcraft and probably many other older applications working with Hamachi are below. These instructions are Windows specific. Although the method should probably work on other platforms.
The main tip is to make Hamachi the first network interface that Windows tries to use. On other platformsthe goal would be the same. Only the way you accomplish it would be different.
1. Go into control panel then click on “network connections”
2. Click the “advanced” link in the menu
3. Click “advanced settings”
4. Change the order so it looks something like this

5. Reboot Windows
After taking these steps Hamachi and Starcraft played nice together.
