title: UDP client multicast address
body: <p>I am developing a system that is sending UDP packets using LWIP on Nios processor. I have developed a C# application to allow visualization of the received data.</p>
  
  <p>The issue that I am having is on receiving data on the C# application when sending to multicast addresses. On the com+uter running the C# app I am able to visualized the incoming packets addressed for IP 225.0.0.1(multicast address) but my C# app does not receive them.</p>
  
  <p>The C# app receives data sent to a network address, for example 192.168.0.100 or when data is sent to 255.255.255.255 (in this case I can run the app in two diferrent computers and both receive the same data).</p>
  
  <p>I have read several answers here on the forum and tried them all.</p>
  
  <p>The code that I am using currently is: </p>
  
  <pre><code>UdpClient udpClientImage;
  
  IPEndPoint RemoteIpEndPoint = new IPEndPoint(IPAddress.Any, 8884);
  
  udpClientImage = new UdpClient(RemoteIpEndPoint);
  udpClientImage.EnableBroadcast = true;
  
  IPAddress m_GrpAddr;
  m_GrpAddr = IPAddress.Parse("225.0.0.1");
  udpClientImage.JoinMulticastGroup(m_GrpAddr);
  
  
  while (true)
  {
      Byte[] receiveBytes = udpClientImage.Receive(ref RemoteIpEndPoint);
  
      senderIPAddress = RemoteIpEndPoint.Address;
      string returnData = Encoding.ASCII.GetString(receiveBytes);
  }
  </code></pre>
  
  <p>Am I missing something in order to receive the multicast addresses?</p>
  
  <p>Any help would be welcome,</p>
