What Happened to the “NAT” VMSwitch?

Hi,

I am trying to run Docker Swarm in Hyper-V VM Windows Server 2019.  I have installed Docker EE and Enabled swarm.  When I deploy my stack to Swarm, my containers do not get outbound connectivity with the Overlay network that gets created.   I referred to this article https://docs.microsoft.com/en-us/virtualization/windowscontainers/container-networking/network-drivers-topologies  I couldn't understand what it means by the comment for Overlay external connectivity "Not directly supported - requires second container endpoint attached to NAT network on Windows Server 2016 or VFP NAT rule on Windows Server 2019."  Can you explain exactly the steps required to make overlay network work with outbound connectivity to internet.  

Thanks
