Virtual networking

[nmpcs]

Is there any possibility of this game working in a virtual network?
I have a few friends who wanted to play a lan game over the internet and as we're playing with the 3b version (4b lags too much on some computers), we can't access the online servers/games, so virtual networking seemed to be the answer.
We tried Hamachi but it doesn't seem to work.
Will any other kind of this type of programs ever work?

Use Tunngle. http://www.tunngle.net/index.php?l=en#l=en&pg=downloads. Once you set it up, look in the Network explorer section on the left and click on the Simulation section.  You will find a Kart racing pro lobby. Click on it and your good to go. Gives you chat function and shows who's in the lobby also. I've used this a few times with 4b and works fine.
