NodeJS UDP Multicast How to

Question

I'm trying to send a UDP Multicast Packet to: 230.185.192.108 so everyone subscribed will receive. A bit stuck. I believe it's broadcasting correctly, but can't seem to pick anything up with any client.

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
