Creating a virtual cloud network (VCN) and public-facing subnets
To create a VCN and public-facing subnets:
- In OCI, go to Networking > Virtual Cloud Networks, and click Create Virtual Cloud Network.
- In the NAME field, enter the VCN name. Then, select CREATE VIRTUAL CLOUD NETWORK PLUS RELATED RESOURCES. This allows you to create the Internet gateway, routing table, and subnet all together using Oracle default settings. If you intend to create each resource separately by specifying your own inputs, click CREATE VIRTUAL CLOUD NETWORK ONLY. In this example, the first choice is used.
- Click Create Virtual Cloud Network at the bottom of the screen.
This configures the related resources. There are three subnets, each of which will belong to an availability domain. They can be defined as public-facing networks (connecting to the Internet). In this example, (1) is 10.0.x.x/24. You can access the FortiGate over the Internet once it is deployed via HTTPS through the GUI management screen or via SSH.
