      Is this module currently working?
      I have a DHCP based private network and thus my WAN address change from time to time. To keep the address to the pfsense updated (as it runs OpenVPN for me), I thought I'd use the DDNS feature of pfsense and use the Cloudflare module.

      But pfsense kept sending DNS updates with PUT verbs, which Cloudflare blocks does not accept; it seems to only accept PATCH for updating records; I could see in my Cloudflare logs that it seems to sends the correct data and ip address but that cloudflare denies it cause it's a PUT and not a PATCH. Could be something else wrong too I guess.

      I think I must have missed something.
      Surely this is a fairly common DDNS combo to run.

      P.S.
      I fixed my problem by writing my own C# service, that checks my public IP every now and then and compares it to what Cloudflare DNS setting is.
      If needed, it then updates it (by sending a PATCH post request).
      It runs from a windows box from behind the pfsense box.

        @Euroguy Cloudflare DDNS is working correctly for both IPv4 and IPv6 on v25.07.1 for me.

        What version of pfSense are you running?
