To determine why some applications are blocked from communicating in the network, check for the following:. A user with sufficient privileges receives a query notification advising them that the application needs to make a change to the firewall policy. Not fully understanding the prompt, the user cancels or dismisses the prompt. A user lacks sufficient privileges and is therefore not prompted to allow the application to make the appropriate policy changes. Local Policy Merge is disabled, preventing the application or network service from creating local rules.
Creation of application rules at runtime can also be prohibited by administrators using the Settings app or Group Policy. Rule merging settings control how rules from different policy sources can be combined. Administrators can configure different merge behaviors for Domain, Private, and Public profiles. The rule merging settings either allow or prevent local admins from creating their own firewall rules in addition to those obtained from Group Policy.
In the firewall configuration service provider , the equivalent setting is AllowLocalPolicyMerge. If merging of local policies is disabled, centralized deployment of rules is required for any app that needs inbound connectivity.
Admins may disable LocalPolicyMerge in high security environments to maintain tighter control over endpoints. This can impact some apps and services that automatically generate a local firewall policy upon installation as discussed above.
For these types of apps and services to work, admins should push rules centrally via group policy GP , Mobile Device Management MDM , or both for hybrid or co-management environments. As a best practice, it is important to list and log such apps, including the network ports used for communications.
Typically, you can find what ports must be open for a given service on the app's website. For more complex or customer application deployments, a more thorough analysis may be needed using network packet capture tools. In general, to maintain maximum security, admins should only push firewall exceptions for apps and services determined to serve legitimate purposes. We currently only support rules created using the full path to the application s.
