I'm trying to play LAN games with my friends who live in other countries, but not using the Nintendo Wi-Fi Connection. We tried RadminVPN, even disabling the firewall and following all the other basic setup requirements (for playing Mario Party DS and Mario Kart), but even though we can all see each other in the game interface, we get an unknown error when we try to connect to the lobby. I'm aware that the software itself mentions not expecting a VPN to solve these problems. Does anyone know if there's anything we can do to fix this? (A specific VPN service or configuration maybe)
