I am using http-auth-request-module on a nginx proxy to authenticate against another server. This other server's authentication mechanism evaluates the requesting client ip adress for authentication purposes.

However, this server only receives the ip adress from the proxy server - regardless from which client i access the proxied URL.

How can i pass the origin client ip adress via the proxy server on to the "authentication server"?

server {
listen *:80;

location /restricted {
auth_request /auth;
proxy_pass http://proxied-server/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

location /auth {
proxy_pass http://authentication-server/;

Client ip adress gets lost (nginx authentication via sub-request)
