321
+ <p>If you have a chain of two or more reverse proxies between your server and the public Internet, you must specify <em>all</em> of the IP address ranges (in CIDR format) of all of your proxy servers, load balancers, etc. Otherwise, Bad Behavior may be unable to determine the client's true IP address.</p>
322
+ <p>In addition, your reverse proxy servers must set the IP address of the Internet client from which they received the request in an HTTP header. If you don't specify a header, <a href="http://en.wikipedia.org/wiki/X-Forwarded-For">X-Forwarded-For</a> will be used. Most proxy servers already support X-Forwarded-For and you would then only need to ensure that it is enabled on your proxy servers. Some other header names in common use include <u>X-Real-Ip</u> (nginx) and <u>Cf-Connecting-Ip</u> (CloudFlare).</p>
