I am deploying Fortigate Standalone on GCP, FG deployment was successful.
In GCP we have created 4 VPCs (unprotected, protected, App & DB). VPC peering is configured between protected vpc to App vpc and between protected vpc to DB vpc via versa.
Between App VPC & DB VPC we are unable to communicate.
Communication between APP VPC & DB VPC should happen via Fortigate.
How we can achieve the same ?
