Hi all!

I recently noticed some unidentified devices connecting to my network, so I decided to change access to my network from block list to whitelist mode. However, I then noticed that this only works on a Wi-Fi level, since my devices that are connected by cable did not require to be whitlisted in order to stay connected.

This makes me wonder what would happen if someone connects a computer to one of my Deco's ethernet ports. The only thing stopping them from accessing my network is the password, since the whitelist mode won't stop them afterwards. 

I'm I wrong?
