Fortigate on AWS

[rubensanchez]

I recently deployed a virtual appliance on AWS, in a simple way. I can add network interfaces from the same Availability Zone in which I deploy the appliance, but I cannot add a network interface from another Availability Zone, and therefore cannot communicate with the subnets in this zone. Is there any way that by deploying the virtual appliance in Zone A, I can access and direct traffic to Availability Zone B?

Can someone help me?, I can't understand what the point of high availability in different zones is when deploying a virtual appliance. If one of them goes down, can't it access the subnets of another availability zone?
