How to disable CloudFlare + UnitPay verification?

Question

PHP

Hello, using the payment system there is a CloudFlare checkout page.
1) Why are requests not coming from their addresses?
2) How to disable for example this page for 1 sprit or IP?

Moderators, please do not delete, edit. I want to solve this problem :(

Answer 1

1. Requests are proxied through cloudflare servers.
2. You don't need to disable anything. The maximum in the firewall of the cloud is to prescribe a rule for passing without checking for unitpay IP addresses.
The client's ip is passed by the cloudflyer in the HTTP_X_FORWARDED_FOR header
