title: I get an error EHOSTUNREACH when trying to connect 1 openshift application in NodeJS with MySQL of another openshift application
body: <p>I have 2 applications on OpenShift: 1 with MySQL, and 1 with NodeJS that is going to connect to MySQL of the other app.</p>
  
  <p>I've seen examples but none of them seem to work, these are the steps I'm taking:</p>
  
  <p>rhc ssh -a mydbappname</p>
  
  <p>then i get the enviroment variables with 
  env | grep MYSQL</p>
  
  <p>I get something like:</p>
  
  <p>OPENSHIFT_MYSQL_DB_HOST=127.XX.XXX.X</p>
  
  <p>OPENSHIFT_MYSQL_DB_PORT=3306</p>
  
  <p>After that i try to use those on the other app, but it always throws EHOSTUNREACH, no matter if i create the OPENSHIFT_MYSQL_DB env variables on the Node app and use them, or if i put it directly on the code.</p>
  
  <p>I have seen in other parts that the OPENSHIFT_MYSQL_DB_HOST is something like 54d10be2503e36378e0002db-mydbappname.apps.rhcloud.com.</p>
  
  <p>If I use the port-forward and use 127.0.0.1 with the local port selected for mysql, and start the NodeJS application locally it works, only when i upload the changes to Openshift it fails</p>
