The Firewall service uses the IFWXFilter interface to load and initialize a filter and to create session filters. An IFWXFilter interface is called for each filter that is in ISA storage and is enabled.
|QueryInterface||Returns pointers to supported interfaces.|
|AddRef||Increments the reference count.|
|Release||Decrements the reference count.|
|FilterInit||Called by the Firewall service when the filter is starting.|
|FilterShutdown||Called by the Firewall service when the service is stopping.|
|AttachToSession||Called by the Firewall service when it determines that a session filter is needed.|
This interface is implemented by the application filter.
This is the interface that is used to create the filter object; therefore, every filter must initially implement this interface. Only one instance of the IFWXFilter object is created per filter.
