I have VMware Workstation 12.1 Pro installed on a Windows 10 64-bit host.
I created a port forwarding rule for VMnet8 (NAT network). I can confirm through netstat that the ports in LISTEN state on the host. I can confirm the guest ports are also working.
As soon as I attempt to open a connection to the forwarded port from the host, the VMware NAT service dies.
If I restart the NAT service, the ports are open again and, again, it will die once I try to connect.
Here are the relevant messages from the event viewer:
