    Description

      It's not possible to bind two listeners to two distinct network interfaces using the same port

      listeners=ONE://<ip1>:9092,TWO://<ip2>:9092
advertised.listeners=ONE://<hostname1>:9092,TWO://<hostname2>:9092
listener.security.protocol.map=ONE:PLAINTEXT,TWO:PLAINTEXT

      Kafka server returns an error:

      [2019-12-02 13:07:18,256] ERROR Exiting Kafka due to fatal exception (kafka.Kafka$)
 java.lang.IllegalArgumentException: requirement failed: Each listener must have a different port, listeners: ONE://<ip1>:9092,TWO://<ip2>:9092
