And I set my Firewall like that, that it only accepts Cloudflare IP's. But it rejects Cloudflare too and I dont get any Cloudfalre IP's logged that got rejected
there's two types of CF Proxy IPs, the incoming ones (anycasted ones in your proxied a/aaaa records) and the outgoing ones (which CF uses to connect to your origin)
well, how would it though? It hasn't made a connection yet? Some connections are Argo Smart Routed, how would it know which IP that would come out of? The only utility that shows Edge Server Origin IPs is HTTP Logpush iirc
