Hi, i got a domain for whoch i defined proxied dns in cloudflare, i was expecting cloudflare traffoc will hide the client IP and change it to cloudflare IP pool bot when i display the whole request it seems that IP wasnt changed at all, I was expecting i could use this change to limit the traffic only to cliudflare

What are the steps to reproduce the issue?

yu can check it by entering https://scrab.pl/request.php it will display the whole request value to the screen together with client IP,

The Cloudflare proxy doesn’t hide the client IP, it hides the origin server IP from clients.

By default the client IP is passed in headers as your page shows. If you want to remove client IPs from the headers to anonymise your users, you can use this managed transform…

If you mean you want to prevent traffic bypassing Cloudflare by going direct to your origin, then you need to block all but Cloudflare IP addresses for port 80/443 at your origin firewall or use Authenticated Origin Pull.
