Proxy ip address

What are the ip addresses that I need to open as incoming to my origin servers?

from what i see - this list is equivalent to opening all internet :slight_smile:
I was wondering if one of CF plans allows private IP address or at least smaller range…

Not really, that’s from the Internet. These are Cloudflare addresses and the list you asked for. You just need to whitеlist them.

Since it’s a shared IP address, an attacker can easily come from Cloudflare to attack the origin server directly (bypassing CF).

Not really, you just need to whitеlist these addresses and not allow others.

You can also use Tunnel, but white​listing the address should work just fine.
