load balancer/reverse proxy?

[gabrielt]

Hi there,

I use a software load balancing but the idea is the same.

You have to edit class_core.php

and change from:

/**
* Fetches the IP address of the current visitor
*
* @return string
*/
function fetch_ip()
{
return $_SERVER['REMOTE_ADDR'];
}

To:

/**
* Fetches the IP address of the current visitor
*
* @return string
*/
function fetch_ip()
{
return (getenv(HTTP_X_FORWARDED_FOR))
? getenv(HTTP_X_FORWARDED_FOR)
: getenv(REMOTE_ADDR);
}

Also don't forget to edit your lighttpd configuration (lighttpd.conf) in order to log the user IP address. At this file you need to replace %h with %{X-Forwarded-For}i on the accesslog.format line. Example:

From:
accesslog.format = "%h

To:
accesslog.format = "%{X-Forwarded-For}i

Cheers,
Gabriel.
