Before you even get to the CNI, I think AWS VM to internet is at least 3 NAT layers.
So we have 3 layers from container to pod. The virtual host kernel is tracking those layers. Once connection to one container is 3 tracked connections. Then you have whatever else you put on top to go in and out of the internet.
The funny think to me is HaProxy recommended getting rid of connection tracking for performance while everyone is doubling down on that alone and calling it performant.
