Vagrant et nodejs HttpServer

Bonjour à tous, tout d'abord je tiens à remercier Grafikart pour les tutos qu'il fournit, pendant mes années d'autodidactat, tu m'as appris pas mal de choses et tu m'as apporté une nouvelle vision du developpement. Trève de flatteries :P J'ai actuellement un petit soucis que je n'arrive pas à résoudre, j'ai fais mes recherches sur la toile mais rien de bien concluant, en effet j'ai une vm vagrant générée avec Puphpet avec node.js d'installer mais dès lors que je souhaite accèder au serveur http de node via l'ip du serveur vagrant j'ai une erreur timeout sur mon navigateur. Voici mon fichier Yaml:

Par la suite j'accède donc a mon fichier js via la commande de lancement de serveur donc

node app_nd.js

Jusque là aucuns soucis particulier et mon problème de timeout surgit, je suis donc un peu perdu et je solicite l'aide de quelqu'un

En attendant Je vous souhaite à tous une agréable journée.
