title: Terraform: aws_lb_listener with multiple ports
body: <p>I am building an ALB on AWS using Terraform. The ALB should forward multiple ports to the instances, but <a href="https://www.terraform.io/docs/providers/aws/r/lb_listener.html" rel="nofollow noreferrer">the documentation</a> specifies:</p>
  
  <blockquote>
    <p>port - (Required) The port on which the load balancer is listening.</p>
  </blockquote>
  
  <p><strong>Do I have to add a separate ALB listener for each port, or is there a way to specify multiple ports per listener?</strong></p>
