transit_gateway_fortigate_ngfw

AWS Transit Gateway VPC Network

• This terraform plan builds an AWS Network Environment using Transit Gateway and FortiGate NGFW

Network Structure

Hub-Spoke Design utilizing Transit Gateway

• firewall Virtual Private Cloud
• protected Virtual Private Cloud
• management Virtual Private Cloud
• public Virtual Private Cloud
• dmz Virtual Private Cloud

Instructions

• define region, supernet cidr, network prefix, transit gateway options, firewall options and vpc names for network in the terraform.tfvars file
• Use of this module will require setting up Terraform AWS Provider & AWS-CLI (along w/credentials setup etc) before running terraform init
