Add Listeners to an Elastic Load Balancer


To add listeners to an existing Amazon Elastic Load Balancer (ELB).

Table of Contents


  • An existing ELB
  • 'actor' user role privileges
  • To add a Listener for SSL communications, you'll need a Server Certificate.


When you first create a new Elastic Load Balancer, it's automatically set up with one listener already predefined.  By default, an ELB will be configured to listen over HTTP on port 80 and forward traffic to port 80 on the receiving EC2 instances, which are typically your application servers.

  • HTTP; 80->80

If you wish to add additional listeners or make changes to existing ones, you can do so under the Listeners tab of an ELB. 



Go to Clouds > AWS Global > Load Balancing.

Select an existing ELB from the list.

Click the Listeners tab.

In order to add a Listener, you must specify the following information:

  • Protocol - The routing transport protocol that will be used by the ELB.
    • TCP
    • HTTP
    • HTTPS
  • Load balancer port - External port that the ELB will listen on to accept client requests.  Valid ports are 80, 443, 1024-65535.
  • Instance port - The port that the ELB will use to send traffic to the application instances.  Valid ports are 1 to 65535.  The Instance Port does not have to match the Load Balancer Port.
  • SSL Certificate (for HTTPS only) - Select the Server Certificate that will be used for encryption purposes.  See Server Certificates.
