This image shows a virtual firewall on Oracle Cloud Infrastructure.

This image shows aOracle Cloud Infrastructure Region with two virtual cloud networks (VCNs) that span a single Availability Domain.

The first VCN (10.0.0.0/16) contains a firewall VM (virtual machine) and provides an internet gateway and a dynamic routing gateway (DRG). The VCN includes the following subnets:

• Public subnet (Management), 10.0.1.0/24. VNIC-1 connects the virtual firewall with this public subnet. The subnet has security lists.
• Public subnet, (Untrusted), 10.0.2.0/24, includes a VM. VNIC-2 connects the virtual firewall with this public subnet. The subnet has security lists.
• Private subnet (Trusted), 10.0.3.0/24, includes a VM. VNIC-3 connects the virtual firewall with this private subnet.

The second VCN (10.1.0.0/16) includes the following subnet:

• Private subnet (Trusted), 10.1.1.0/24, includes a virtual machine VM. VNIC-4 connects the virtual firewall with this private subnet.
