I would like to use PiHole DNS (on a local Raspberry Pi) as my DNS server. However anytime I enter it as the DNS server my Archer A7 immediately goes offline. This worked fine previous and seems to have started after recent firmware updates. From what I've seen on other pages this may be due to DNS rebind protection potentially added as "Enhance device security" in the 2020-11-04 firmware, and as a result these units don't allow DNS servers to be on the same subnet any longer, but I see no way to disable it. Can someone please put up instructions on how to allow an Archer A7 unit to use local DNS. If not I'll be tossing out my unit and 3 others my family uses to replace them with something that is PiHole compatible. Thanks.
