[7048P] Configuration between PC and internet box with VLAN

Hello,

I come to ask for your help because I am stuck on a case of my network connection to the internet via a box.
I have a PowerConnect 7048P switch, having all the IT elements connected and cut by VLANs.
VLAN 2 corresponds to the VLANs of the internet boxes,
VLAN 6 corresponds to PCs.
By activating the inter VLAN routing, all my hardware can ping between them except for the Internet box.
Could someone tell me where my setup is not correct.
