Get client real IP

Hello, I have traefik behind cloudfare load balancer and my requests are received in the application with cloudfare IP, just like explained in this document

I couldn't find how to manage to get original IP on my app with traefik, I saw some third party pluggins but they didn't work, does somebody have this resolved who can share how to achieve it?

Thanks in advance

You can usually get the original IP from the HTTP headers.

Yes, but how you do it with traefik?

Check if Cloudflare supports proxyprotocol, that works with Traefik.
