401 = Raw Ethernet
Local Host hex 8 The IP address of the local computer (IPv4).
Remote Host hex 8 The IP address of the remote computer (IPv4).
Local Port hex 8 The TCP/UDP port of the local computer (host byte-order). It is only valid on
TSE_TRAFFIC_TCP and TSE_TRAFFIC_UDP. For other events, it is always zero.
Remote Port hex 8 The TCP/UDP port of the remote computer (host byte-order). It is only valid on
TSE_TRAFFIC_TCP and TSE_TRAFFIC_UDP. For other events, it is always zero.
Packet Length hex 8 Lenght of packet data
Direction hex 8 The direction of traffic (unknown = 0; inbound = 1; outbound = 2).
Action hex 8 Specifies if the traffic was blocked (yes = 1, no = 0).
Unknown hex 8 Will require further investigation as to the purpose of this log entry.

system.
Packet varbinary 2000
Rule nvarchar 512 The name of the rule that was triggered by the event. If the rule name is not
specified in the security rule, then this field is empty. Having the rule name can
be useful for troubleshooting. You may recognize a rule by the rule ID, but rule

specified in the security rule. This field is helpful to security rule troubleshooting.
If multiple rules match, it logs the rule that has the final decision on PacketProc
(pass/block/drop).
