We have a business account configured in Cloudflare (let’s say main.com).
We have a need to “proxy” a subdomain from another organization that does not use Cloudflare (dev.com), in a way so it goes through main.com
I mean if users hit sub.dev.com → in fact it goes on Cloudflare and our server (main.com) serves responses.
We have permission to configure records for sub.dev.com in a way we need (without changing dev.com records).
I have read a lot a found this article (seems to be possible but requires 200$ plan+)
Also I found that it kind of possible to add CName record on sub.com side like this (that did not work):
CNAME shop.sub.com => main.com.cdn.cloudflare.net
Could anybody give me advise if that is possible and what would be the right way to do it?
Thanks.
