DESCRIPTION


IMPORTANT NOTE:Running this cmdlet without parameters enables all Windows Firewall rules on the target computer. Always run this cmdlet with the -WhatIf parameter if you are
not targeting a specific Windows Firewall rule or group of rules.


The Enable-NetFirewallRule cmdlet enables a previously disabled firewall rule to be active within the computer or a group policy organizational unit.


This cmdlet gets one or more firewall rules to be enabled with the Name parameter (default), the DisplayName parameter, rule properties, or by associated filters or objects.
The Enabled parameter for the resulting queried rules is set to True.

EXAMPLE 3

PS C:\>Enable-NetFirewallRule –Direction Outbound -PolicyStore contoso.com\gpo_name



This example enables all of the previously enabled outbound firewall rules in a specified GPO.




EXAMPLE 4

PS C:\>$nfwRule = Get-NetFirewallRule -PolicyStore ActiveStore -PolicyStoreSourceType Dynamic
