How to get this working?
reread your thread topic, and explain to us what you want to do ...
I have installed adguard home on my windows pc. How to get dns working on my openwrt??
by installing adguard home on the router instead ?
No. My adguardhome is on my pc.
is the computer on 24/7 ?
if not, then having the router use it is pretty .... stupid.
Yes. My pc is on 24/7
does the router have to use it, or is it really for your remaining clients ?
I want the router my to use local dns
your router isn't the local DNS, if it's actually the 24/7 PC ?
I mean my pc as dns server
https://openwrt.org/docs/guide-user/base-system/dhcp_configuration#dhcp_options option 6.
this is for your clients though, not the router itself.
