title: is is possible to use stunnel / spiped to secure Redis Cluster?
body: <p>What is the proper way to ssl secure a Redis cluster? (Client-server, node-node communication). </p>
  
  <p>As mentioned in Redis cluster specification, every node on the cluster listens on 2 ports: the port for "external" communication and another for the cluster bus. 
  According to this, each node should have 2 stunnels - accepting on a "fake" port and connecting to "external" \ cluster bus port?</p>
