The FwxFirewallEventType enumerated type contains values that specify the types of events raised by the Microsoft Firewall service for which a filter may receive notifications. Each value in this enumeration represents a single bit. Values can be combined by using the bitwise OR operator to specify a set of events.

typedef enum FwxFirewallEventType

  fwx_Connect_Tcp = 0x00000001,
  fwx_Udp_Destination = 0x00000002,
  fwx_Bind_Tcp = 0x00000004,
