Direct IP access not allowed cloudflare in nginx proxy server - nginx

Question

I have one site in openshift rhc ,So i want to make one reserve Proxy with nginx software in Openshift Rhc servers, which from this server have access to many other server with nginx so i configured my nginx server by this kind of configuration :
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
error_log {{OPENSHIFT_HOMEDIR}}/app-root/logs/nginx_error.log debug;
pid {{NGINX_DIR}}/logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;

I used Upstream index:
upstream index {
server free-papers.elasa.ir weight=1;
server diy4tornado-tornado4ss.rhcloud.com weight=2;
}
but when i use this configuration ( with cloudflare or rhc server) i get this error from cloudflare:
Direct IP access not allowed cloudflare
So what is proper configuration for nginx or Apache server software for this kind of servers.
Thanks a lot for your attentions.

Answer 1

i found the answer:
gzip on;
gzip_min_length 1000;
gzip_proxied expired no-cache no-store private auth;
gzip_types text/plain application/xml application/javascript text/javas$
gzip_disable "msie6";
gzip_http_version 1.1;

Important things is proxy header Host:
