I noticed that the PowerShell New-NetFirewallRule cmdlet does not behave like I expected. When calling the commandlet repeatedly, it will create multiple entries with the same name.
For example, when running this command twice New-NetFirewallRule -DisplayName "Website" -Direction Inbound -LocalPort 80 -Protocol TCP -Action Allow, will give two of the same firewall entries.
Should commands with the New verb not fail when the resource already exists?
When New-NetFirewallRule retuns an object with the firewall rule, Set-NetFirewallRule returns nothing.
Running Set-NetFirewallRule does not work for creating a new rule. It will raise an error which says that the resource does not exist. I expected a Set verb updates or creates the resource.
