What is the issue you’re encountering

I want to know the IP range of the edge network, to install a firewall rule on my origin server

What steps have you taken to resolve the issue?

Since my origin server is proxied its IP address is not revealed but it is still possible to send requests to it if you know its IP address

I want it to only be possible for Cloudflare to connect to the server, by adding a firewall rule on the origin server itself (not within Cloudflare)

Is that possible? I would need to know the IP range of my edge network in order to to allow only that range on port 443

Was the site working with SSL prior to adding it to Cloudflare?

Yes

What is the current SSL/TLS setting?

Full (strict)

What are the steps to reproduce the issue?

n/a

Allow all of these ranges…

Note that Cloudflare only proxies HTTP/HTTPS (unless using Cloudflare Spectrum) so port 22 can’t be used with the proxy.

Thank you, and that was a typo, I meant to write 443
