IFWXFirewallAction Interface

The IFWXFirewallAction interface cancels a firewall action.

Syntax

interface IFWXFirewallAction : IUnknown

Methods

The IFWXFirewallAction interface inherits the methods of the IUnknown interface.

In addition, IFWXFirewallAction defines the following method.

Method	Description
Cancel	Cancels a Microsoft Firewall service action.

Remarks

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:

• Actions that are supposed to happen only once (the action is canceled after its first occurrence).
• Actions that have a time-out.
• An action associated with a session that has been killed.

Requirements

Server	Requires Windows Server 2008.
Version	Requires Forefront Threat Management Gateway (TMG).
Header	Declared in Wspfwext.idl.
