And i need to bind my UdpClient to one of them ( and listen to him )

How do i do it ?

Answer 1

That binds UdpClient to specific network interface.

var portNum = 2000; // your port
var ipAddress = IPAddress.Parse("192.168.0.1"); // your IP
var listenEndpoint = new IPEndPoint(ipAddress, portNum);
var myClient = new UdpClient(listenEndpoint);
