[7048P] Configuration entre PC et box internet via VLAN

Bonjour,

Je viens vous demander votre aide car je suis bloqué sur un cas de connexion de mon réseau à l'internet via une box.

J'ai un switch PowerConnect 7048P, ayant l'ensemble des éléments informatiques connectés et découpés par VLANs.

Le VLAN 2 correspond donc aux VLANs des box internet,

Le VLAN 6 correspond aux PC.

En activant le routage inter VLAN, tous mes matériels peuvent faire un ping entre eux à l'exception de la box Internet.

Est ce que quelqu'un pourrait me dire où ma configuration n'est pas correcte.
