title: Node.js is not accessible from external IPs on Ubuntu
body: <p>I try to access my node.js server running on Ubuntu. My PC is connected with TP-link router. Now, I want to access node services from other IP(not from my local host or local IPs). What can I do? I used following code.</p>
  
  <p>Note: This server works fine and accessible from local IP but can't access from my public IP</p>
  
  <pre><code>http.listen(6000,"0.0.0.0",function(){
      log.info("server started");
  })
  </code></pre>
