Launching FortiGate-VM on AWS
The most basic deployment consists of one FortiGate-VM with two elastic network interfaces (ENIs) facing a public subnet and private subnet, with the FortiGate-VM deployed inline between the two subnets. A single FortiGate-VM protects a single virtual private cloud (VPC) with a single availability zone (AZ). The public subnet's default gateway is an AWS Internet gateway, and the FortiGate-VM's private subnet-facing ENI is the private subnet's default gateway. Protected EC2 instances such as web servers, database servers, or other endpoints are assumed to exist in the private subnet. One elastic/public IP address or IPv4 DNS name must be allocated to the FortiGate-VM in the public subnet for you to access the FortiGate-VM remotely via HTTPS or SSH over the Internet for initial configuration.
