title: How can I allow access to a single IP address via Nginx.conf?
body: <p>Nginx, Passenger, and Rails are running beautifully on my Linode. Before I launch, I'd like to restrict access so only my IP can view the site. </p>
  
  <p>I've tried to deny access to all, and allow access to only my IP in Nginx. It does deny access to all, but I can't get the allow to work. I have checked to ensure the IP address I'm specifying in nginx.conf is my correct public ip.</p>
  
  <p>Here's my nginx.conf. I've restarted nginx after editing the file, and tested some other changes which worked as expected (for instance, I removed deny all and was able to access the site, as expected).</p>
  
  <p>What am I doing wrong?</p>
  
  <pre><code>    http {
        passenger_root /path/to/passenger-3.0.11;
        passenger_ruby /path/to/ruby;
        include       mime.types;
        default_type  application/octet-stream;
        sendfile        on;
        keepalive_timeout  65;
        gzip  on;
        server {
          listen 80;
          server_name www.foo.bar;
          root /path/to/rails/public/;
          passenger_enabled on;
          location / {
            allow   my.public.ip.here;
            deny    all;
          }
        }
      }
  </code></pre>
