AX73: Router changes IP if I set the dns to local resolver
I recently acquired the AX73 model and it has one issue that is a bit frustrating.
I do not want to use my ISP dns and I need to use my own resolver that is present inside the network. This resolver gets the dns record via DoH from Cloudflare.
I have associated ip 172.16.0.1 for the router.
When I try to go to Advanced->Network->Internet->Advanced Setting->Primary DNS and set the ip of my resolver to 172.16.0.11, the router changes its IP back to 192.168.0.1 and displays a message that in order to avoid IP conflicts, IP of router has been changed(which is not the case).
How can this issue be solved?
