We are pleased to announce that Elastic Load Balancing now supports all ports as well as additional Access Log fields that improve your visibility into application request traffic.
Load balancers within a VPC no longer limit the available ports but allow for any port,between 1 and 65535, to be specified. As a result, or Elastic Load Balancing can now be used together with applications and protocols that require a specific port to be used.to memorize more,visit http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/elb-listener-config.html.
