Asus AX86u block DoT traffic?

[josh3003]

Hi just wanting to know if I have prevent client auto DOH enabled is there another option or command to prevent devices from accessing DoT as I have DNS Director enabled.

DNS Director effects both DNS (53) and DoT (853).

if I have prevent client auto DOH enabled

This one is an attempt only, mostly Firefox browser. It won't stop client doing DoH. Blocking known DoH servers does better job. You need something like Pi-hole with stock Asuswrt. More on-router options with Asuswrt-Merlin (Diversion, AdGuard Home).

prevent devices from accessing DoT

You can block port 853 in firewall, if you want to.

I got the DOH lists on pihole so it should be good then in that sense. Ok thank you.
