Creating VPC networks

This configuration requires three virtual private clouds (VPC) for the FortiGate: external, internal, and mirroring. It also requires a fourth VPC where you deploy the VM instances whose traffic will be mirrored. This guide refers to the fourth VPC as "VPC 1".

To create the VPC networks:

1. In the GCP console, go to VPC Networks, then click CREATE VPC NETWORK.
2. In the Name field, enter the desired name.
3. From the Region dropdown list, select the region appropriate for your deployment.
4. From the IP address range field, enter the first network's subnet in CIDR format, such as 10.0.1.0/24.
5. Leave all other settings as-is, then click Create.

   

6. Repeat steps 1-5 to create the remaining three VPCs.
7. Go to Compute Engine > Virtual machines > VM instances. Deploy two VMs to VPC 1.
