How to handle network load balancer health checks when using dynamic ports with UDP traffic?

0

My setup: 1 NLB (UDP traffic) using dynamic port mapping to ECS tasks.

Question: The NLB only sends health checks on the mapped port and only as TCP, HTTP, HTTPS. My ECS task definition maps my container's port to the host port using UPD. This works fine, however, I'm unable to add an additional mapping, on the same port, for TCP. I'm also unable to use a custom health check port because dynamic port mapping is enable.

That said, how should NLB health checks be handled when using dynamic port mapping and UDP traffic?
