Still can’t understand why not Add-VMNetworkAdapterAcl.
Can you please explain it to me?
To my understanding Add-VMNetworkAdapterExtendedAcl cmdlet creates an extended access control list (ACL) for a virtual network adapter while Add-VMNetworkAdapterAcl just creates ACL because when a virtual network adapter is created there is no ACL on it. So, why not just Add-VMNetworkAdapterAcl?

That’s because you have to specify the inbound port 3389 (Add-VMNetworkAdapterExtendedAcl … Inbound -LocalPort “3389” …) and Add-VMNetworkAdapterAcl allows only IP-based ACLs.
