title: restrict access to the admin url by ip in django with nginx and gunicorn
body: <p>I am trying to restrict access to the admin section of my django app by using simple host-based access control in nginx. 
  Unfortunately nginx does not seem to abide by the configuration request:</p>
  
  <p>this is my setting for this particular section in nginx:</p>
  
  <pre><code># gunicorn setup
  location / {
      proxy_pass http://127.0.0.1:8000;
      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 /admin/ { # restrict access to admin section
      allow 192.168.0.1;
      deny all;
   }
  </code></pre>
  
  <p>This does still block my ip 192.168.0.1.
  What am I doing wrong?
  Is there another way to block access to the /admin/ section of a django app?</p>
