Create subnets in the VPC

To enable different IP network addresses on internal and external interfaces of the firewall, you have to create two subnets in the VPC.

Creating the public subnet

  1. In the VPC Dashboard, select the Subnets menu.
  2. Click on Create a subnet.
  3. Fill in the following fields:
  • Name tag: Stormshield public in the example,
  • VPC: select the previously created VPC (10.6.0.0./16 in the example),
  • IPv4 CIDR block: indicate the IP subnet (10.6.0.0/24 in the example).
  1. Click on “Yes, Create”.

Creating the private subnet

Repeat steps 2 and 3 with the following values to create the private subnet:

  • Name tag: Stormshield private in the example,
  • VPC: select the previously created VPC (10.6.0.0./16 in the example),
  • IPv4 CIDR block: indicate the IP subnet (10.6.1.0/24 in the example).
