title: Assign port number manually for each connection
body: <p>I'm running a server (say on port 50000). Any new request is accepted and a random port is assigned by OS each time. I want to manually assign the port number instead of system doing it randomly for me.</p>
  
  <p>The main reason for this is I'm trying to do some multicast thing based on port number. I'm planning to assign few clients on same port. Next slot of clients on another port and so on.</p>
  
  <p>Any idea?</p>
