workerman 能设置制定ip链接么

<?php
use Workerman\Worker;
require_once './Workerman/Autoloader.php';
$ws_worker = new Worker("websocket://0.0.0.0:2346");
$ws_worker->onConnect = function($connection) {
    if($connection->getRemoteIp() != 'xx.xxx.xx.xx') {
        $connection->close();
    }
 };
$ws_worker->onMessage = function($connection, $data) {
        $connection->send('hello ' . $data);
};
Worker::runAll();
