Help: pihole local DNS record transfer to Opnsense router (social.fossware.space)

Im trying to setup a DNS record in Opnsense to forward ex:( ***.local.mydomain.com ) to (192.168.1.777(nginx proxy)) but every option in Opnsense that I try it doesn't forward to my reverse proxy machine.

I have Unbound,AdguardHome and wireguard installed on the Opnsense.

Unbound port is 53 Adguard port is 5353

I tried going to: Services>Dnsmasq DNS>settings>host override, but it didn't seem to work I also tried logging to AdguardHome>filter>DNS rewrite, but it also didn't seem to work

What am I doing wrong, when I type (nslookup *.local.mydomain.com) I only get the response "server can't find *.local.mydomain.com"

Solved!!

In Opnsense I created a rule to forward my domain to an IP. You just need to go to Services>unbound>overrides>host overrides and add your domain

If you have adguard on port 53 that will be your first hop and main DNS server. If you setup rewrite on adguard to point *.local.my domain.con to 192.168.1.777 that should be good. Next ensure your DHCP server sets correct DNS server for clients.

https://docs.opnsense.org/manual/dhcp.html

Next I would ensure that the client you’re testing with is pointing to the adguard DNS. In this case your open sense router on port 53.

Depending what you’re testing with on Linux you can check /etc/resolv.conf

You can run dig command to point directly to your adguard server to verify it works and you have connectivity

dig @192.168.1.1 something.local.my domain.com

Thank you that was very informative, I went through again and found out that my Unbound is using the port 53 and Adguard is using 5353.

That means Unbound is the main DNS server on my case. Where would I put my (*.local.domain.com to 192.168.1.**) rule

edit: I followed a guide on how to install Adguard with unbound. https://youtu.be/7RC7q5WOYC0

Since unbound is your primary DNS where clients connect, set the override there.

Where would I have to input my domain name

Go to Services > Unbound > Overrides, and add a host override. Then you'll get a window to put the host, domain, and IP.
