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( is DHCP server, where I have reserved IP address ( 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?

  • Please, post you complete configuration, the output for the ping test (you are mentioning it) and also a traceroute/mtr output.

  • Do tcpdump -ni eth0 and then ping (in a different terminal). If you see no outgoing ping packets, the problem is on the PiHole, so next step is ip route get to verify you've no other rules that interfere. If you see outgoing packets, but no response, the problem is elsewhere, probably on the router.

  • I cant do tcpdump, because is not installed and is not possible to download it.

Thank you all fo you, guys. Incident solved. There was some bug on my home gateway, which disconnected this device after 20 seconds after what i did any changes in home gateway. I did upgrade firmware on my home gateway, did factory reset and set up it again and everything works well.

Thank you all for your time. Cheers
