Windows Server 2019 running Docker/Swarm, ingress network was working fine until this was installed:
2020-05 Cumulative Update for Windows Server 2019 (1809) for x64-based Systems (KB4551853)
This broke something with the ingress network such that no traffic could enter through any exposed/published ports, either from the local machine or remotely.
Uninstalling this update made it all work again.
Deploying containers on the nat network worked fine. Access from the containers to the external network remained working in a docker swarm, but no traffic could come in.
