title: How to make MySQL RDS available to only my IP?
body: <p>In AWS, I set up an RDS which was originally not publicly available. I set it up using <a href="http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/TUT_WebAppWithRDS.html" rel="nofollow noreferrer">this tuturial</a>. The Apache server that resulted is publicly accessible; the MySQL instance is not.</p>
  
  <p>Now I'm trying to modify access to the RDS to make it where I can get to it with <a href="https://en.wikipedia.org/wiki/HeidiSQL" rel="nofollow noreferrer">HeidiSQL</a>.</p>
  
  <p>I've added the RDS to the public security group, and tried a few other mods to no effect.</p>
  
  <p>I'd like make this where it can be accessed only from my IP. But in an attempt to just get a connection, I've set it right now where the security group has it wide open. However, when I try to connect from HeidiSQL or Telnet using port 3306, no TCP connection is established.</p>
  
  <p>Here is the configuration. Any idea what I'm missing?</p>
