Since today 2021-07-21 my temp rule activated via powershell seems don't work anymore i receive the following error:
PS C:\WINDOWS\system32> New-NetFirewallRule -DisplayName "Block Outbound Port 80" -Direction Outbound -LocalPort 80 -Protocol TCP -Action Block
New-NetFirewallRule : The requested object could not be found.
At line:1 char:1
+ New-NetFirewallRule -DisplayName "Block Outbound Port 80" -Direction ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (MSFT_NetFirewallRule:root/standardcimv2/MSFT_NetFirewallRule) [New-NetFirewallRule], CimException
+ FullyQualifiedErrorId : MI RESULT 6,New-NetFirewallRule
This example is also mentioned into https://docs.microsoft.com/en-us/powershell/module/netsecurity/new-netfirewallrule?view=windowsserver2019-ps
looks like the final part trig error : -Action Block
As request in comment this is the output:
PS C:\WINDOWS\system32> Get-NetFirewallRule -DisplayName "Block Outbound Port 80"
Get-NetFirewallRule : No MSFT_NetFirewallRule objects found with property 'DisplayName' equal to 'Block Outbound Port 80'. Verify the value of the property and retry.
