Can the Firewalla block randomized MAC addresses from WIRED devices?  Can it be set to either block them entirely or assign them to a default group with minimal privileges?

  If you ever figure out a way to block devices with randomized mac addresses i will be a happy camper.

   

  Ok, I know this is not what you want, BUT:

  Use "New device quarantine".

  Restore internet to the quarantine group, but set up smart queue, then limit the bandwith the group has, to 1mbit or whatever else you desire..

  Isn't this exactly the new device quarantine is for? https://help.firewalla.com/hc/en-us/articles/360058853313-Firewalla-New-Device-Quarantine

  Today, it doesn't distinguish between none randomized and randomized MAC, but it still works perfectly to quarantine anything that's new. (randomized MAC)

  Thanks for the replies. I just wanted to make sure that the Firewalla can do this for WIRED devices. A lot of routers advertise this, but it only works for wireless devices. For example, on my ASUS XT9 I can set up a MAC whilelist but it's only for WiFi, not wired. 

  So, it appears that the only devices that can do this are the Gryphon and the Firewalla. 

  EDIT: It looks like I could use 1. Firewalla (in router mode) with my ASUS XT9 (in AP mode), or 2. Gryphon AX.

  Just to confirm, New Device Quarantine works with both wireless and WiFi devices? I would think of course it does since it's not even doing the WiFi at all, but I have to ask anyway.
