Create VPCs
To create your VPCs and subnets, login to the GCP Console.
In the Navigation menu, expand VPC network and select VPC networks.
Click CREATE VPC NETWORK.
Type a name, description (optional) and set the Subnet creation mode to Custom.
Type a name for your subnet.
Expand the Region menu and select the region for your subnet.
Type the IP address range for your subnet. Example: 10.0.1.0/24.
Scroll down and click Done for the subnet.
Scroll down and click CREATE.
Note: Starting with NIOS version 8.6, instances can be deployed with either one or two NICs. For older NIOS versions, two NICs and two VPC networks are required when deploying vNIOS for GCP appliances. If required or desired, repeat the above steps to create a second VPC network with a subnet in the same region, using a different address range.
Wait and verify that your VPC network(s) are created successfully.
