title: Access to Jenkins using public IP address
body: <p>I've installed Jenkins on my <a href="http://Amazon%20AWS" rel="nofollow noreferrer">AWS</a> Windows system. I am able to access it within a system using <a href="http://localhost:8080/" rel="nofollow noreferrer">http://localhost:8080/</a>, but I can't access it outside the system using the public IP address.</p>
  
  <p><a href="http://xxx.xxx.xxx.xxx:8080/" rel="nofollow noreferrer">http://xxx.xxx.xxx.xxx:8080/</a></p>
  
  <p>My <a href="http://en.wikipedia.org/wiki/Amazon_Elastic_Compute_Cloud" rel="nofollow noreferrer">EC2</a> instance is assigned with the public IP address.</p>
  
  <p>I've changed the URL in the Jenkins system configuration too.</p>
  
  <p>How can I access Jenkins from outside the local system? I need the Jenkins' public access URL for linking it with GitHub WebHook.</p>
