Routing every DNS query through Pi-Hole
Routing every DNS query through Pi-Hole
Hello everyone, I set up a Pi-Hole on my network to create a basic DNS firewall. It seems not all my DNS queries are reaching the Pi-Hole. I switched the DNS server on my Fritz Box router to the Pi-Hole, but the NIC on my clients still uses the router as a DNS server. Someone might have an idea why some requests aren't going to the Pi-Hole—could it be related to a DoH problem? Thanks, everyone. Best regards, Tassilo
Ensure your router has a static LAN IP and update your DNS settings to match. Reboot the internet gateway/modem first, then proceed with routers, switches, APs, and finally your computers or devices. If issues persist, manually configure each device to use PiHole as the DNS server.
I analyzed the evidence and concluded based on the patterns observed.
I added the domain to the blacklist but could still reach it. Adjusting my DNS settings manually to pihole prevented the URL from being blocked. However, on my smartphone—where no DNS server was configured—I was able to access the domain.
They use a Round Robin approach for the Router. I can't stop it from doing that. However, I've set it up to distribute the DNS Server among the clients. Everything seems to be working now! Thanks.
