title: Accessing Ruby Server on amazon instance from my browser
body: <p>I have started the Ruby on Rails tutorial and am on my first app. I did all of this on an instance I have on amazon web service (aws). A while ago I installed apache on there so when I put in the public address (port 80) it tells me 'It works'. I want to access this server from my web browser at home.</p>
  
  <p>However when I put in the server address :3000 (the port the app should be running at) I get nothing. Do I need to tell the box to open port 3000 or something of the like? </p>
