NGINX forward visitor real ip to apache

let’s assume u have

NGINX on port 80

apache on port 8080

in nginx config -> sever config -> virtualhost config

location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
proxy_pass http://127.0.0.1:8080;

}

so your apache logs say traffic   comes from IP 127.0.0.1
