Turris.omnia w/ time capsule via wifi

i have an time capsule which i want to connect via ethernet directly to turris omnia.
Better to say it is connected.

My Macbook is connected via my wifi which is bridged w/ the lan.

If i want to look up on the settings via the foris wui i can’t see its there connected.
I also can’t see it via its AirPort utility.

I set the ports on the firewall for this briged network (lan and wifis - 2.4 Ghz + 5 Ghz).

Does any has an idea to get the TimeCapsule connectable via wifi from the lan port?
