You have deployed a FortiGate HA cluster in Azure using a Gateway Load Balancer for traffic inspection. However, traffic is not being routed correctly through the firewalls.
What can be the cause of the issue?
A. The Fortinet VMs have IP forwarding disabled, which is required for traffic inspection.
B. The health probes for the Gateway Load Balancer are failing, which causes traffic to bypass the HA cluster.
C. The Gateway Load Balancer is not associated with the correct network security group (NSG) rules, which allow traffic to pass through.
D. The protected VMs are in a different Azure subscription, which prevents the Gateway Load Balancer from forwarding traffic.
