FWPM_ENGINE_OPTION enumeration (fwpmtypes.h)

The FWPM_ENGINE_OPTION enumerated type specifies configurable options for the filter engine.

Syntax

typedef enum FWPM_ENGINE_OPTION_ {
  FWPM_ENGINE_COLLECT_NET_EVENTS = 0,
  FWPM_ENGINE_NET_EVENT_MATCH_ANY_KEYWORDS,
  FWPM_ENGINE_NAME_CACHE,
  FWPM_ENGINE_MONITOR_IPSEC_CONNECTIONS,
  FWPM_ENGINE_PACKET_QUEUING,
  FWPM_ENGINE_TXN_WATCHDOG_TIMEOUT_IN_MSEC,
  FWPM_ENGINE_OPTION_MAX
} FWPM_ENGINE_OPTION;

Constants

FWPM_ENGINE_COLLECT_NET_EVENTS Value: 0 The filter engine will collect WFP network events.
FWPM_ENGINE_NET_EVENT_MATCH_ANY_KEYWORDS The filter engine will collect WFP network events that match any supplied key words.
FWPM_ENGINE_NAME_CACHE Reserved for internal use. Note  Available only in Windows Server 2008 R2, Windows 7, and later.
FWPM_ENGINE_MONITOR_IPSEC_CONNECTIONS Enables the connection monitoring feature and starts logging creation and deletion events (and notifying any subscribers). If the ETW operational log is already enabled, FwpmEngineGetOption0 will return showing the option as enabled. FwpmEngineSetOption0 can be used set the value (but fails with FWP_E_STILL_ON ERROR when attempting to disable it). Note  Available only in Windows 8 and Windows Server 2012.
FWPM_ENGINE_PACKET_QUEUING Enables inbound or forward packet queuing independently. When enabled, the system is able to evenly distribute CPU load to multiple CPUs for site-to-site IPsec tunnel scenarios. Note  Available only in Windows 8 and Windows Server 2012.
FWPM_ENGINE_TXN_WATCHDOG_TIMEOUT_IN_MSEC Transactions lasting longer than this time (in milliseconds) will trigger a watchdog event. Note  Available only in Windows 8 and Windows Server 2012.
FWPM_ENGINE_OPTION_MAX Maximum value for testing purposes.
