Creating an internal network subnet
To create an internal network subnet:
- Let's create an internal protected network, where VMs will be placed under the FortiGate’s protection. Click Create Subnet.
- Let's create the internal protected network in the availability domain where the FortiGate is located. Choose the appropriate domain in use, then enter the internal subnet. The route table must be the one created earlier for the internal network. Under SUBNET ACCESS, select PRIVATE SUBNET. You can select any security list as desired. In the example, a security list that allows all protocols for any source and destination was selected. You must create the security list prior to this configuration.
