21.1 Legacy Series / Re: [Solved] Help troubleshooting why DNS over UDP does not reach DNS resolver
« on: May 05, 2021, 03:46:54 pm »Advantage of this setup is I can see which requests are coming from which device ip's on the local network. Disadvantage of this setup is for now I've lost the DoH/DoT/DoQ that is configured out of the box on AdGuard Home and not replicated on Unbound by default.

This Unbound DNS guide is pretty good and was recently modified to include 'tls-cert-bundle' that properly checks for valid certificates. The problem I have is Unbound can be kind of buggy and unreliable. I have resorted to enabling a PiHole as a DNS backup, with Cloudflared DoH. If you start having issues with Unbound, you might want to bypass it.
