Tunngle is a p2p VPN that allows you to play online games with your friends over LAN. It's totally free and it works awesome. Nort and I have already tunngled each other multiple times playing AoW2. Nort couldnt get his shit together creating an internet game so we could game. I said fuck this shit and told him to download tunngle. He was suspicious, stating he didnt want me to hack his computer, but downloaded it anyway.
