DNS WAN change to PiHole - Reseting router

2021-12-30 23:22:25

Model: Archer AX1800

Hardware Version: V2

Firmware Version: 2.1.2 Build 20210901 rel.75681(4555)

I'm having a bizarre behavior when I change the DNS on the WAN to my PiHole, It just reboots itself and changes the network address.
What is going on? Am I missing something here? Is there anyway to disable this "smart" feature?

@Nano.Bautista

The router won't allow you to set WAN interface DNS with IP address from the router's LAN subnet.

You should set the Pi-hole IP address in the DHCP server settings (e.g Primary DNS Server):

@terziyski that's exactly what I did, the problem with that solution is that when I connect the VPN through the router I got a DNS Leak as it uses the DNS of the DHCP.

i was able to change the DNS of the WAN on previous routers, it feels that is just bad design or maybe the problem that I'm having with the VPN is a bug, as one would imagine that all requests should be using the VPN DNS and not the DHCP.

Any advice on that?

I don't know if when using the routers VPN client, DHCP DNS is used instead of VPN DNS, is a bug or not.

But for sure the inability to use LAN IP address for DNS on the WAN interface has been restricted by device's FW.
