In my setup I am using Citrix NetScaler as a reverse proxy.</p> <p>Simular to when you&rsquo;re using a 3rd party reverse proxy such as <a href="https://www.cloudflare.com/">CloudFlare</a> you will see the IP address from the reverse proxy instead of the actual Client IP Address on your webserver.</p> <p>This means that your logging will all show the same, internal, IP address and that IP Based Access Rules will not work.</p> <p>Fortunately this is easy to solve by having NetScaler add the Client IP Address in the headers and rewriting the address on your webserver.</p>
