I had to trim the script a little to make it work. Once you have your Cloudflare account setup the info required is easy to locate:Ī-record ID for your domain (this is obtained by running the cloudflare-dns-id.sh script) Make sure you create the DNS entry for the domain name you want to update on CloudFlare the DIUP action parameter will only update the IP for an entry that already exists. Instead of using HTTP basic auth I just use a random key. $curl = '$hostname&u=$username&tkn=$api&ip=$ip' URL: /cloudflare_update.php?key=&hostname=Ĭloudflare_update.php if(empty($_GET) || ($_GET != '')) die DD-WRT DDNS settings DDNS Service: Custom The way I have it configured is to have DD-WRT call a PHP script on a remote web server, which then detects the client IP and sends the update request to CloudFlare via their API. I don't think you can set it up where DD-WRT calls CloudFlare directly. URL from 'Location' works perfectly and parameter 'a' is included.
