How can I make ServerSocket accept multiple connections from same IP?

I have a server socket that accepts connections and passes them off to a worker thread. This works concurrently when the connections come from different IP addresses. It will not accept a new connection from any given machine (ip address) until the previous connection is closed by that client.

How can I make this work?

Thanks in advance.

Edit: The requests from the same ip client will block until the previous completes.

    private ConcurrentLinkedQueue<WorkerThread> queueList = new ConcurrentLinkedQueue<WorkerThread>();

...

public void ServerSocketLoop()
{
    try
    {
    ServerSocket sk = new ServerSocket(iPort);
    while (!sk.isClosed())
    {
        Logger.Log(this, Logger.CONNECTION_ONLY, "Loop: ");
        int cnt = getQueueList().size();
        Socket clientSocket = sk.accept();
        String clIp = clientSocket.getInetAddress().getHostAddress();
        boolean match=false;
        if(!allowedIps.isEmpty())
        {
            for(String alIp : allowedIps.keySet())
            {
                if(clIp.startsWith(alIp))
                {
                    match=true;
                    break;
                }
            }
        }
        else
            match=true;
        if(match)
        {
            try
            {
                Logger.Log(this, Logger.CONNECTION_ONLY, "Accepting connection from: " + clIp);
                WorkerThread scs = new WorkerThread(clientSocket, this);
                getQueueList().add(scs);
            } catch (Exception e)
            {
                Logger.Log(this, e);
            }
        } else
        {
            Logger.Log(this, Logger.CONNECTION_ONLY, "Refused connection from: " + clIp);
        }
    }
    }
    catch(Exception e)
    {
        Logger.Log(this, e);
    }
}

Edit: More information.

The worker thread once started reads the (client) socket input stream, uses process builder to execute a command with the data read through the socket writes the results back through the output stream of the socket then closes the socket.

Well dang, my test program was broken. Not to try to understand if the client side (PHP) is the culprit.

Old program.

echo "one" | nc -C localhost 5554
echo "two" | nc -C localhost 5554
echo "three" | nc -C localhost 5554
echo "four" | nc -C localhost 5554
echo "five" | nc -C localhost 5554

New program.

echo "one" | nc -C localhost 5554&
echo "two" | nc -C localhost 5554&
echo "three" | nc -C localhost 5554&
echo "four" | nc -C localhost 5554&
echo "five" | nc -C localhost 5554&

Thanks for all your answers. Sorry to waste your time.

There is nothing magical about allowing a ServerSocket to accept multiple requests from the same IP. In fact, it will happen naturally ... and it looks like your code will do that.

However, your code (as shown) is creating threads but not starting them. Unless you start a thread, its run() method won't run.

(I assume that WorkerThread is a subclass of Thread.)

In other words, you are already accepting the request connections, but it is doubtful that it is reading and processing the requests.

For what it is worth, it is a BAD IDEA to write your worker logic by extending the Thread class. It is better to implement the Runnable interface, and pass that as a constructor argument to a plain Thread object. Or better still use something like a ThreadPoolExecutor with a bounded thread pool to manage the creation of threads and queuing of requests.
