title: Communication socket on python
body: <p>I'm learn about tcp/ip communication. I make some requirement like this</p>
  
  <pre><code>Client 1 -&gt; hardware (1.1.1.1, 62093)
  Client 2 -&gt; client.py (12.12.12.12, 5234)
  Server 3 -&gt; server.py (12.12.12.12, 5000)
  </code></pre>
  
  <p><code>Server</code> can receive data from <strong>Client 1</strong> and <strong>Client 2</strong> but when I try send data from <strong>Client 2</strong> to <strong>Client1</strong> it can't connected. It's possible to send data from <strong>Client 2</strong> to <strong>Client 1</strong> ? If not possible how do <strong>Client 1</strong> send data to <strong>Client 2</strong> ?</p>
  
  <p>If someone have an idea please tell me, it will be helpful,  Thanks</p>
