When http server is behind rev-proxy, then IP address point to rev-proxy IP, not real user IP. I propose add small hack:
In /src/commands/connect.class.php after line:
// store the user ip
add lines:
// by AM: adding proxy logging
$ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
if (empty($ip)) {
$ip = $_SERVER["REMOTE_ADDR"];
}
Now Admin see real user IP.
