UniFi USG DNS not working with DHCP clients : Ubiquiti
www.reddit.com › r › UbiquitiBut clients just don't behave that way in dns. And if your local dns server on the usg goes down, then I doubt you'll be able to reach 8.8.8.8 anyways (as the whole usg is likely down). Either way, the usg will use 8.8.8.8 to get any records it doesn't know itself, so you're probably already getting the dns behavior you're looking for.
