title: Kafka Server Properties - unable to connect to broker
body: <p>Lets say Kafka is running as a single node broker on an AWS EC2 instance. The instance has the internal private IP <code>10.0.0.1</code>. I want to connect to that broker directly from the same EC2 instance and from another EC2 instance in the same VPC and subnet. The security groups are allowing the connection. 
  Which settings do I have to use to get the connection running? </p>
  
  <p>I tried <code>listeners=PLAINTEXT://0.0.0.0:9092</code> and <code>advertised.listeners=PLAINTEXT://0.0.0.0:9092</code>. With that setting I can connect to the broker from local (the same instance where the broker is running), but I can't reach the broker from the second EC2 instance. </p>
  
  <p>Does anybody have any idea? </p>
