title: Spark standalone master behind the vpn
body: <p>I have a Spark standalone master running on a machine in the AWS VPC binding to the private IP address. I'm able to run spark jobs from the machine inside the VPC but not from my laptop that is connecting to the cluster via VPN. I checked executor logs on a spark worker and got <code>Cannot receive any reply in 120 seconds.</code>. Looks like networking issue.</p>
  
  <p>Anybody knows how to solve that?</p>
