Hey ShehzadUIT,

 

MMC does not display every Firewall rules, there are multiple stores like Local, GroupPolicy etc. use PowerShell to retrieve the Firewall rules for the "Active Store" and you will find your configured rules:

 

Get-NetFirewallRule -PolicyStore ActiveStore

 

Reference:

Get-NetFirewallRule (NetSecurity) | Microsoft Docs

 

best,

Oliver

Thanks Oliver Kieselbach you have helped me out (again) - would also add to help others that when filtering the results of the PowerShell query use $_.DisplayName not $_.Name as MDM gives the rule a generic string of characters as the name which isn't easy to spot.

 

so Get-NetFirewallRule -PolicyStore ActiveStore | where-object { $_.DisplayName -eq "YourRuleName" } 

 

Will prove that the rule was created successfully
