Hi Trikky.
Are you following this tutorial?:
http://www.emucoach.com/showthread.php?41-How-to-make-server-public-with-Hamachi-Guide!
You simply just open it and follow the step on here:
Now you need to set your hamachi ID to the server realmlist. Go into your DB, HeidiSQL or Navicat, you can use them both. After you logged in, you will see a word called "Auth" click on that, and then click on "realmlist" and edit your "address" It will say 0.0.0.0 now, edit it to your hamachi IP, and save it. (You will have to do that or this wont work. (You can also change your realm name there. Your HeidiSQL or navicat is not needed now, you can close it, it doesn´t matter.
Are you having issues with it, need it more explained? Because I can do so.
