Transparent mode
In Transparent mode, the FortiGate-5001A security system is invisible to the
network. All of the FortiGate-5001A interfaces are connected to different
segments of the same network. In Transparent mode you only have to configure a
management IP address so that you can connect to the FortiGate-5001A security
system to make configuration changes and so the FortiGate-5001A security
system can connect to external services such as the FortiGuard Distribution
Network (FDN).

You would typically deploy a FortiGate-5001A security system in Transparent
mode on a private network behind an existing firewall or behind a router. In the
default Transparent mode configuration, the FortiGate-5001A security system
functions as a firewall. No traffic can pass through the FortiGate-5001A security
system until you add firewall policies.
