Rx40 with internal Lan dos attack?

I don't understand why there would be a dos attack from a chromcast audio.

I also see one line for my main computer everytime I wake it up. I've run malwarebytes and bitdefender (paid versions) to make sure everything is clean.

It could likely be a false detection, I’ve seen Steam, Apple and even Amazon servers as sources on my RAX120 along with internal sources. Leads me to believe it’s buggy. I would just disable the DDoS protection feature.
