Java - How to accurately get the ip address of the requestor

We are currently working on a program to catch automated attacks (brute force, DoS etc.). We wanted to have a 2nd level handling of it next to Firewall handling. We already developed a logic but the problem is how to accurately get the ip address of the requestor.

The request passes through the ff:

Request -> firewall -> web server -> mobile app server -> app server for APIs(where our web service is deployed).

Its also possible the request can be behind a proxy. With this is it still possible to get the correct ip address of the requestor? so it could be blocked.

You web server maybe nginx, consider Using the Forwarded header.But you can only get the ip of the proxy server when the request behind a proxy, because it limited by the tcp/ip layer mechanism.
