Hi,
i enabled AdGuard DNS in Asus router WAN settings:
TUF-AX5400-DNS1.png


It works see: https://adguard.com/en/test.html

TUF-AX5400-DNS2.png

(I have to disable iCloud Private Relay on MacOS to make it work)


But there is still something wrong:

When i check traffic in Terminal all is still send over DNS (Port 53) and not DNS-over-TLS (Port 853)

The setting DNS-over-TLS doesn't make sense if i can't force traffic over it. Or am i missing another setting to activate DNS-over-TLS?
My ASUS LAN -> DNS settings are empty.

:-/

Your router is acting as DNS proxy. It sends upstream requests using DoT. You don't have DoT between the router and your devices on LAN.
 
Port 853 is the default. You do not need to add it. Also, I recommend you alternate the IPV4 and IPV6 addresses. Stubby, the application that does the DoT, cycles through the list of upstream resolvers. To see if it is working log into the router with a terminal and run: stubby -l To cancel the "log" do "Ctrl c"
