title: Symmetricds one way setup
body: <p>I am a little confused on how to setup a one way 3 tier replication using symmetricds.</p>
  
  <p>What I am trying to setup is something like this:</p>
  
  <p><a href="https://i.stack.imgur.com/QqDfi.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QqDfi.jpg" alt="Setup"></a></p>
  
  <p>The company server is not connected to the internet and as you can see it's one way, and basically the final tier is a readonly database used by a web application . </p>
  
  <ul>
  <li>How to setup this 2 steps replication?</li>
  <li>Do I need to install Symmetric (java . etc) in each server? </li>
  </ul>
  
  <p>Need some guideline here, thanks.</p>
