Re: flaw only affected those users with custom DNS setups on their personal networks.
A while ago, Unifi APs started calling home to the vendor to report stats.
Now my Unifi APs have their management address on a separate VLAN, which blocks *all* outgoing traffic. The controller sits on this VLAN too. And I only open up outbound access from the controller when fetching a new firmware version.
It's sad that we can't trust vendors not to spy on us these days.
