Listeners tab

The Listeners tab allows you to specify the protocol and ports that the Elastic Load Balancer (ELB) will use to send/receive traffic. When you first create a new ELB, 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)

For SSL communications, select the 'HTTPS' protocol and select a Security Certificate.

  • 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 (SSL) encryption purposes.
