Using ngx_http_access_module behind a load balancer

Server NGINX
#1

Hi guys,

I’m using nginx behind a load balancer, and I receive the user IP in
X-Client-IP. I would like to setup some rules with
ngx_http_access_module, and I would like to know if it’s possible to
make nginx use X-Client-IP for the http access test (right now nginx
believes the real IP of the client is the IP of the load balancer).

Thanks!
