Alright, So hopefully I am just doing something wrong here. But I'm literally pulling my hair out because how irritating this issue is.

 

Basically I created a dns lookup server on my local network using dnsmasq and a raspberry pi. But I can't get this router to use it without issues.


So just to walk through this. I first set a reserved ip address for my pi.

I then go to the dns settings and change the primary to my pi's ip.

After saving this though, We have an issue almost immediately. The gateway says it has an ip address conflict and has to change the default ip address from 192.168.0.1 to 192.168.1.1. Which is fine. So i let it do its thing. And reconnect to the web portal from the new ip address. But here starts the big issue.

My reserved ip address has been disabled. And my raspberry pi is connected at (192.168.0.147) now

And essentially this is a loop that continues. If i change the primary dns record to look at 192.168.0.147, Then the same thing will happen and the gateway change back to 192.168.0.1, which causes the pi to go back to 192.168.1.147.

The dns server itself seems to be working fine though

So any ideas whats going on with this router?

Hi,

 

The WAN side of a router (named "Internet" here) and the LAN side of a router cannot both have IP addresses that fall within the same subnet. That's technically not possible.

 

If you want your local client devices to be assigned the local DNS server's IP address, then you have to put this information in the "DHCP Server" section.

 

I agree that the behavior of the AX11000 seems a bit weird. I believe most other routers will just refuse outright to accept any LAN network IP address to be entered in the WAN ("Internet") configuration.
