J'utilise Ubuntu 14.04 et j'essaie de mettre en place une pptp VPN entre moi et un serveur. J'utilise network-manager pour ça.
Maintenant, le VPN fonctionne parfaitement lorsque je suis en ligne. Ethernet alors que le WiFi mon ordinateur portable ne sait pas comment atteindre le serveur (même si ping fonctionne comme prévu) :
