Xmage+Tunngle=Internet Match?

Hi all, english is not my first language so please, be patient
I love this program and i'm trying to find a good way to play online with friends without using public server.
Server doesn't work under NAT router, so i thought about just creating a virtual LAN, using an external software (Tunngle).
With Tunngle is possible to emulate a LAN through internet, have new ip addresses of the same lan and start a server session only changing serverAddress parameter under config.xml with the ip given by Tunngle.
Anyone interested could help me testing? If someone did it before i'm sorry for the repost
Thanks ^^
