Managing Firestick Traffic

I just found a bunch of noisy traffic on my network coming from 192.168.49.1 - my Firestick.  Unfortunately, another security tool identified that and I never saw it from my Firewalla Gold.

Is there anyway to see / monitor / manage traffic such as that? Is this a L2 issue?

This is tshark from the Firewalla Gold CLI.

This is the finding from "another" tool that has an agent on my laptop.
