Question

My server doesn’t have a public IP address, so I don’t know how to get the real client’s IP address.

This is my nginx’s configuration:

location / {
    proxy_pass http://domain1;
    proxy_set_header        Host            $host;
    proxy_set_header        X-Real-IP     $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
}

In my Rails app’s controller both request.ip and request.remote_ip return my server’s gateway address.

How can i get the real IP of client?

How to get X-Forwarded-For value from Rails request?

Answer 1

You should get the header value X-forwarded-for
