Comment(by nacin):

 Cross referencing [15560] as well as this potential snippet, good for wp-
 config.

 {{{
 if ( ! empty( $_SERVER['HTTP_X_FORWARDED_FOR'] ) && preg_match(
 '/^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/', $_SERVER['HTTP_X_FORWARDED_FOR']
 ) )
         $_SERVER['REMOTE_ADDR'] = $_SERVER['HTTP_X_FORWARDED_FOR'];
 }}}

 Again, specific to your environment. You also may want to check for
 HTTP_X_FORWARDED_PROTO for HTTPS.
