Using VPN with Dolphin BBA?

[Zerowalker]

Does anyone know how to set up so i can play together with my friends over the internet?
I have tried messing around but i am really bad at this VPN stuff sadly.

I am thinking that i can be the server and my friends connect to me and we have a "LAN",
and then i assume Dolphin will work fine and see the other systems.

The game we want to play is Mario Kart Double Dash.

Thanks
