无法使用PHP从localhost远程连接MongoDB

I am trying to connect MongoDB Server remotely from localhost but unable to connect. I did like below inside my code:

public function connect() {
        require_once 'dbcon/config.php';
        $dbname='koolfeedback';
        $con=new MongoClient('mongodb://10.25.*.*:27017');
        $connect=$con->$dbname;
        $this->db=$connect;
        return $connect;
}

I am running my project inside localhost (Xampp). When I was using mongodb locally it was connecting well but now I need to connect to remote server and unable to do that.

On the remote mongo server you have to bind your IP or set it 0.0.0.0 . Mongo only listens to localhost by default.
