[Questions] About Gl-MT3000, AdguardHome and Openwrt

I bought a year ago a Gl-Mt3000 and have been using it as a home router since then.

It was fantastic, since the interface is really easy, i put all my iot on a guest network, my family cellphones on another and activated Adguardhome with little knowledge needed.

Now, i wanted to start learning a bit more, so i decided to host the dns sinkhole (Adguard Home) by myself on my main network.

I more or less got it working, it shouted a few errors but it worked. My problem is that the iot devices on the guest network can't access it.

Tinkering with the gl-inet interface i was able to proxy all dns request to the Adguard server, but since they are redirected from the router i lose the statistics since every query appears as if it was done by the router itself.

From what i read, there are ways to make the udp 53 port reach the guest network but it flew a bit over my head, and i don't know how touching luci will mess with the gl-inet interface. Edit: You can easily do this through the gl.inet interface, on the tab called port forwarding, you can forward between zones, not only to the internet, i don't know why it didn't occurred to me. In my defense i wasn't able to google either. Maybe it was too obvious.
