Set up VDSL with 1and1 Provider

im trying to setup an CDSL connection with my 1and1 Provider in Germany.
I have an VDSL Modem in Slave mode, but no connection.

I found some hints vlan7 tag, but no dedicated information about that.

Pls give me some information about setting a vdsl connection with turris router and vlan7 tag, in best case straight forward for all steps


Hi Stefan,
I have my Turris router with a Vigor 130 modem connected to 1und1. VLAN with ID 7 must be set. I have do this set directly at the modem. You can also make the VLAN tagging with the Turris. It is described here:
