I have nginx up and working with pihole and its great. I can get to: https://dashy.homelab.duckdns.org/ On my PC but not my phone. On my phone, pfsense blocks it and says “Potential DNS Rebind attack detected, see https://en.wikipedia.org/wiki/DNS_rebinding Try accessing the router by IP address instead of by hostname.”
Why? I’ve disconnected and reconnected to WiFi, and waited a day.
Including the local DNS settings? Like mapping my domain to an ip?
I mostly meant the DNS sinkhole functionality that pihole is famous for using to block ads. You wouldn’t use pfblocker-ng for domain routing.
Here is a forum post from negate discussing what I think you’re looking for.
