Hello. I recently flashed my TPLink AC1750 router to Openwrt and am having trouble connecting my wired devices to use a local dns server (running on a rpi). All the wireless devices can connect to the server; however, the wired devices are still going through the router and using the default dns. It is a settings in the router gui which I cannot figure out how to setup. I have tried a few suggestion, but it is not working.
Previously when I was running the stock tplink firmware, I was able to set the wired device to use a specifi dns server from the internet protocal 1pv4 properties. This is what I see in windows cmd prompt under servers line. 192.168.1.10 is what I want to use.
One option is to advertise that nameserver with option 6 of dhcp. Make sure that you do the same with ipv6.
I would suggest, however, instead of that, to keep OpenWrt as nameserver for your lan hosts and add a line of configuration in dnsmasq to forward the local queries to the other nameserver. For example:
