Trust an application using the Firewall Event Viewer

If you use role-based administration:

You must have the Policy setting - firewall right to configure a firewall policy.
You cannot edit a policy if it is applied outside your active sub-estate.

For more information, see Managing roles and sub-estates.

If the firewall reports an unknown application or blocks an application on your networked computers, an event is displayed in the Firewall Event Viewer. This topic describes how to trust an application from the Firewall Event Viewer and apply the new rule to your chosen firewall policies.

To find details of reported or blocked applications in the Firewall Event Viewer, and trust them or create new rules for them:

On the Events menu, click Firewall Events.
In the Firewall - Event Viewer dialog box, select the entry for the application you want to trust or create a rule for, and then click Create Rule.
In the dialog box that appears, select whether to trust the application or create a rule for it using an existing preset.
From the list of firewall policies, select the firewall policies to which you want to apply the rule. To apply the rule to all policies, click Select All and then click OK.

If you are using checksums, you may have to add the application's checksum to the list of allowed checksums. See Add an application checksum.
You can also add an application as trusted directly in a firewall policy, using the advanced firewall policy configuration pages. See Create an application rule from a firewall policy.
