NLB listener for port range

It is not possible to configure port range on a single listener for an AWS Network Load Balancer (NLB) at this time. NLB listeners are designed to work with a single port per listener.

NLB does not support port range for listeners.

AWS Global Accelerator supportss port ranges for listeners, and is probably more suitable for your use case.

In step 2 of the blog post, notice the two listners for TCP 2000, 2443, 2445, 3804, 5060 and UDP 5060, 16384 – 32767
