I’m on at least 2 blocklists at this point for the crime of not having reverse DNS set up. I don’t know how rDNS works. No amount of reading Wikipedia is helping me understand what I have to do.

  • I have a domain at a registrar which gives me bog standard DNS.
  • I have Apache running on my network.
  • I have PiHole running on my network.

My understanding is that rDNS is not set up at my registrar, but somewhere in my network. What do I do?

Thank you for your time.

    Routing to me has been solved, my router was incorrectly dropping pings on WAN because I messed up the firewall configs. The trouble users still can’t reach my website.

      Your ISP may block 80 / 443. Try moving your webserver to an alternate high port and ask the users to test with that.

        But it’s only very few people. If my ISP blocks these ports, why 99% of people have no issues?

          At this point I’d install wireshark and see if I’m getting their TCP connections at all.

          Given your other routing issues though, I would guess you have another config issue on your firewall.
