title: Secondary IP on Amazon EC2 unreachable
body: <p>I've added a secondary private IP address to my EC2 instance and associated a new elastic IP with it.</p>
  
  <p>My EC2 Instance now lists a single "Public IP" (the original public, elastic, IP) and 2 "Elastic IPs" (the original and the new one I've added)</p>
  
  <p>All good I thought but I can't connect to the server using either HTTP or SSH at this new elastic IP.</p>
  
  <p>I'm guessing that the single security group that's attached isn't being applied to the new elastic IP. </p>
  
  <p>Looking for suggestions of how to debug this (logs?) or make sure the security group applies to both elastic IPs? </p>
  
  <p>Could it be because the new elastic IP isn't listed as "Public IP" ? It's confusing having multiple definitions of what's "public". I've been assuming Elastic = Public</p>
  
  <p>EDIT:
  The server is running ubuntu 14.04.3 LTS</p>
