NodeJS UDP 多播如何

我正在尝试将 UDP 多播数据包发送到：230.185.192.108，以便每个订阅的人都会收到。有点卡住了。我相信它的广播正确，但似乎无法从任何客户端获取任何信息。

Server:

var news = [
   "Borussia Dortmund wins German championship",
   "Tornado warning for the Bay Area",
   "More rain for the weekend",
   "Android tablets take over the world",
   "iPad2 sold out",
   "Nation's rappers down to last two samples"
];

var dgram = require('dgram'); 
var server = dgram.createSocket("udp4"); 
server.bind();
server.setBroadcast(true)
server.setMulticastTTL(128);
server.addMembership('230.185.192.108'); 

setInterval(broadcastNew, 3000);

function broadcastNew() {
    var message = new Buffer(news[Math.floor(Math.random()*news.length)]);
    server.send(message, 0, message.length, 8088, "230.185.192.108");
    console.log("Sent " + message + " to the wire...");
    //server.close();
}

Client

var PORT = 8088;
var HOST = '192.168.0.102';
var dgram = require('dgram');
var client = dgram.createSocket('udp4');

client.on('listening', function () {
    var address = client.address();
    console.log('UDP Client listening on ' + address.address + ":" + address.port);
    client.setBroadcast(true)
    client.setMulticastTTL(128); 
    client.addMembership('230.185.192.108');
});

client.on('message', function (message, remote) {   
    console.log('A: Epic Command Received. Preparing Relay.');
    console.log('B: From: ' + remote.address + ':' + remote.port +' - ' + message);
});

client.bind(PORT, HOST);

Changed:

client.addMembership('230.185.192.108');

to

client.addMembership('230.185.192.108',HOST); //Local IP Address
