Allows administrators to use the Windows Firewall component in Control Panel to define a local port exceptions list. Windows Firewall uses two port exceptions lists; the other is defined by the "Windows Firewall: Define inbound port exceptions" policy setting.If you enable this policy setting the Windows Firewall component in Control Panel allows administrators to define a local port exceptions list.If you disable this policy setting the Windows Firewall component in Control Panel does not allow administrators to define a local port exceptions list. However local administrators will still be allowed to create firewall rules in the Windows Firewall with Advanced Security snap-in. If you wish to prevent all locally created rules from applying use the Group Policy Object Editor snap-in and configure Computer Configuration\Windows Settings\Security Settings\Windows Firewall with Advanced Security to specify that local firewall rules should not apply.
