We have a Hyper-V 2016 server installed on bare metal (not on top of Win2016) so it only has a command-line interface. We need help to configure the built-in Windows firewall to fully open all ports on the internal NIC, and open only ping on the external NIC. We know how to do this in the GUI, but not command-line. Is this something you can help with? It seems like you have a lot of Hyper-V experience. The project is not urgent, so you can definitely do it in your spare time.
