We’re running a website on a sub-domain of zone owned and managed by somebody else outside of Cloudflare. The desire is to implement Cloudflare firewall only on that sub-domain without migrating DNS management of the domain zone to Cloudflare. The owner of the domain zone is willing to do whatever DNS configuration necessary on their end. Is it possible to add a Site on a sub-domain to Cloudflare?
I don’t think it works in that direction (into Cloudflare), only out of Cloudflare.
Edit: Pretty sure, in fact, as Cloudflare won’t work if your domain isn’t using Cloudflare name servers.
