Windows Server 2019 IP Group for Firewall

Question

I have a couple of Windows Server 2016 and 2019 boxes and wish to add some simple rules to the Windows Defender Firewall (e.g. RDP Port, FTP Ports, etc.), allowing a group of IP addresses. I'd prefer not to use Group Policy, but rather just the firewall itself. Is there a way to create a Group of IPs (e.g. 10 ip addresses), and apply the group to multiple rules in the firewall? That way, if any of the IP addresses change, I would only need to update the IP Group, and nothing else.

Answer 1

Power shell would be your best bet.
