Create VPC Networks for GCP

The threat defense virtual deployment requires four networks which you must create prior to deploying the threat defense virtual. The networks are as follows:

  • Management VPC for the management subnet.

  • Diagnostic VPC or the diagnostic subnet.

  • Inside VPC for the inside subnet.

  • Outside VPC for the outside subnet.

Additionally, you may have to set up the route tables and GCP firewall rules to allow traffic flow through the threat defense virtual. The route tables and firewall rules are separate from those that are configured on the threat defense virtual itself. Name the GCP route tables and firewall rules according to associated network and functionality

Procedure

Step 1

In the GCP console, choose VPC networks, then click Create VPC Network.

Step 2

In the Name field, enter the desired name.

Step 3

From the Subnet creation mode, click Custom.

Step 4

In the Name field under New subnet, enter the desired name.

Step 5

From the Region drop-down list, select the region appropriate for your deployment. All four networks must be in the same region.

Step 6

From the IP address range field, enter the first network's subnet in CIDR format, such as 10.10.0.0/24.

Step 7

Accept the defaults for all other settings, then click Create.

Step 8

Repeat steps 1-7 to create the remaining three VPC networks.

What to do next

You may have to create firewall rules to apply to your newly created VPC networks. Go to the GCP console and navigate to Networking > VPC network > Firewall and then click Create Firewall Rule. See GCP documentation for more information.

Once your GCP VPC networks have been finalized, continue on to deploy the threat defense virtual.
