I have a site with Joomla and Moodle which are connected through Joomdle. I installed a firewall on my site and now I have problem that Joomla and Moodle can't connect to each other. I contacted the provider of the firewall and they found that the site was behind a Cloudflare proxy and they needed to whitelist the ip-adresses for that proxy.
Can anyone help me with this, I didn't install any proxy. Is this a default setting for Moodle? If this is the case, what are the ip-numbers?
