The session diagnostic displays an original session path and a reflect or auxiliary session for asymmetric forwarding. The reflect session lists dev=7- > 6/6- > 7; interface index 7 corresponds to port3 and index 6 corresponds to port2, establishing a reply direction of port2 to port3. The original session path dev=7- > 5/5- > 7 represents port3 and port1, not port3 and port2. Auxiliary sessions can be hardware-offloaded when the FortiGate network processor supports the relevant configuration and conditions; a single currently observed offload flag does not prove that capability is impossible. Therefore C and D are the correct conclusions. Reference: FortiOS 7.6 — Controlling Return Path with Auxiliary Session. An operational review should distinguish the rule that matches the traffic from the interface that is ultimately selected. Valid forwarding also depends on destination route eligibility, current member state and the applicable SLA or quality-selection algorithm. A diagnostic showing configured members alone is not conclusive evidence that all those members will carry a particular flow.
