I have on my home LAN network my home router set up as gateway and few clients. One client (orangepipc) works also like DNS resolver with installed PiHole. on the gateway(192.168.11.1) is DHCP server, where I have reserved IP address (192.168.11.6) for PiHole. On the gateway is set up this PiHole as Primary DNS resolver and for all the clients in LAN works fine. I am able to ping the PiHole and join there with SSH from the LAN. But If I am join to the Pihole device, from there is not possible join/ping to the gateway or the other device in LAN/WAN. Oh the PiHole device installed only clean actual Armbian, Kodi and PiHole (from the installation script).
The first, what I checked up is gateway set up misconfiguration on PiHole, but I cant see anything wrong. Attaching my settings bellow. Any ideas, pls?
