title: External access to home Rails server
body: <p>My home server is running on Raspberry Pi with Rasbian (Debian for ARM)
  There rails server is running: <code>rvmsudo rails s -b ${LOCAL_IP} -p 80</code></p>
  
  <p>It works perfectly fine to access from local machines, but it is not working when I am trying to access from outside of my local network</p>
  
  <p>It should not be a router problem as I can easily access that server over ssh (both :22 and :80 are open in router preferences)</p>
