Exam FCP_WCS_AD-7.4 topic 1 question 5 discussion

GWLB ensures that traffic flows are sent to the same appliance to maintain stateful processing. This is critical for the functioning of stateful firewalls like FortiGate, which need to keep track of the state of connections to inspect traffic effectively. GLB and the virtual appliances exchange application traffic with other using GENEVE, which allows GWLB to preserve the content of the original traffic.

Study guide pages 147 and 150.

Inbound and outbound traffic will go to the same device, which will perform stateful processing: The Gateway Load Balancer (GWLB) in AWS ensures that traffic is forwarded to the same FortiGate device for stateful inspection. This ensures that the session remains intact during the processing​. The content of the original traffic exchanged between the GWLB and FortiGate will be preserved: The GWLB uses the Generic Network Virtualization Encapsulation (GENEVE) protocol, which preserves the original traffic content during its transmission to and from the FortiGate device for inspection​. These references confirm that GWLB ensures stateful traffic processing and preserves the content of the original traffic when exchanged between the GWLB and FortiGate appliances.
