Which of the following is NOT an option to calculate the traffic direction?

The option that is NOT an option to calculate the traffic direction is Outgoing. Traffic direction is a parameter that determines how traffic is classified as internal or external based on its source and destination. Traffic direction can be calculated using three options: Incoming, Internal, or External. Incoming means that traffic is classified as internal if its destination is one of the Security Gateway’s interfaces, and external otherwise. Internal means that traffic is classified as internal if its source or destination belongs to one of the internal networks defined in the topology, and external otherwise. External means that traffic is classified as internal if both its source and destination belong to one of the internal networks defined in the topology, and external otherwise. Outgoing is not a valid option to calculate traffic direction.
