title: How configure aws-ec2 Instance to run playframework 1.2.7 application
body: <p>I have deployed our playframework 1.2.7 web application to aws-ec2 ubuntu instance. The started the application on port 8081 since 80 or 8080 complains about not able to bind to those ports. How can I configure the ubuntu instance either througth the aws security group or on ubuntu itself so that I wouldn't have to add the port 8081 to the end of the public url or the public ip provided by aws.
  ie I don't want do this: </p>
  
  <pre><code>example.com:8081 / ip4:8081
  </code></pre>
  
  <p>But I just want to use:</p>
  
  <pre><code>example.com / ip4
  </code></pre>
  
  <p>to access the application.
  Please I need help on this.</p>
