    By rule of thumb you need two VLANs. First for the Internet WAN part:

     

    1. #7 with the link towards the Telekom side VLAN 7, tagged, PVID whatever (I think, no need for handling non-tagged packets there) no other VLAN membership (!!!)
    2. #7 with the link towards the Google WiFi VLAN 7, untagged, PVID 7 - no other VLAN membership (!!!)

    When I understand you right, this does work.

     

    Now it seems you intend to use the switch also for the LAN with a dedicated VLAN. You could use the default VLAN 1. Ensure this is VLAN not on the two ports where Internet/WAN VLAN 7 is. So configure all other ports to VLAN 1, untagged, PVID1 - and no other VLAN membership.

    The static IP (on a LAN IP, like 192.168.1.x or whatever is in use there) is required because the Smart Managed Plus type switches (except some XS variants) don't allow to limit the controller to a single management VLAN. Said tht, there is some risk in this set-up with that switch class.
