Method Description


Cancels a Microsoft Firewall service action.


A filter may request that the Firewall service perform a firewall action, such as connecting to a certain target, based on a firewall event or address. A firewall action is always requested in anticipation of an event that may not occur. This interface permits cancellation of the Firewall service action request. Typically, a firewall action relates only to events for which a filter is not registered.

For example, if the action is the future establishment of a secondary connection, the IFWXFirewallAction interface can be used to cancel the action if the primary connection is terminated.

The firewall may automatically cancel certain actions, including:


Server Requires Windows Server 2008.
Version Requires Forefront Threat Management Gateway (TMG).
