HTTP_X_FORWARDED_FOR

Running wordpress behind pound proxy. Contact Form 7 module special-mail-tags.php and akismet.php currently pull the proxy IP using the SERVER variable REMOTE_ADDR. When emails arrive with IP included using the wpcf7 routine, the proxy IP appears. This may impact the blacklist lookup?

In my case, I can probably just tinker with the modules to set a variable using HTTP_X_FOWARDED_FOR, sort of hard-coding user_ip and replacing the $_SERVER[‘REMOTE_ADDR’] in the modules.

However, maybe the routines should include a typical x-forwarded-for function:
function getIP() {
$ip;
if (getenv(“HTTP_CLIENT_IP”))
$ip = getenv(“HTTP_CLIENT_IP”);
else if(getenv(“HTTP_X_FORWARDED_FOR”))
$ip = getenv(“HTTP_X_FORWARDED_FOR”);
else if(getenv(“REMOTE_ADDR”))
$ip = getenv(“REMOTE_ADDR”);
else
$ip = “UNKNOWN”;
return $ip;
}

Has anyone else done this?
