Direct access to AGH not possible, but through my router

[karlranseierausrom]

Hi,
I have a AVM fritzbox 7530AX, where I have set the DNS server to my HomeAssistant with AdGuard Add-On.

192.168.178.108 is the IP of my Hass/AdGuard.
With this setting all queries go through the router and everything is listed in AGH as if it comes from my router:

In AGH I have set three clients with their IP adresses. Only the router has some counts.

So far everything is correct, because DNS server for every client is my router, as I gathered by using nslookup. The router than uses AGH as DNS-server, if I understand correctly.

The disadvantage is, that I cannot directly apply rules to certain clients (like for my fridge, printer and so on). I want every client connect directly to AGH.

To make every client directly connect to AGH, I have set the local DNS in avm fritzbox firmware:

When I than disconnect and connect any client (android, wind10) it gets no connection to the internet. Using nslookup I found out, that the IP address is correct: 192.168.178.108, so that the client tries to use that as DNS server. Looking up example.org gives an time out for dns resolving.
The same happens when I manually switch to the AGH-IP by nslookup:

Server: homeassistant.fritz.box
Address: 192.168.178.108

DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.

In some dicussions I found out, that cients should be created. I did that, but have not created any rules.
Someone noted, that I have to add

dns:
bind_hosts:
- 0.0.0.0

to the yaml. It did not work, therefore I removed it again.

I have the feeling that I am doing a very stupid mistake. Does someone have an idea what I could do to solve the problem?

Best regards

edit: homeassistant OS on Rpi5. Home assistant is the version of today. AGH version 5.2.2

You need to set the DNS on the LAN/Client settings not the WAN/internet DNS.
