General Information on Interfaces

The Interfaces function shows all network interfaces defined to the machine that the firewall is installed on, and allows the administrator to tell the IBM Firewall which network interfaces are secure and nonsecure. The Secure Interface is that which is connected to your internal network and is the one to be protected. All networks and subnets connected to the Secure Interface are considered secure. All other interfaces listed here are considered nonsecure. If an interface gets added to the Firewall, it will automatically get added to this list and be assigned the nonsecure status.
