Example default route to an external network

Figure 7 shows a FortiGate unit where all destinations, including the management

computer, are located on the external network. To reach these destinations, the

FortiGate unit must connect to the “upstream” router leading to the external network.

To facilitate this connection, you must enter a single default route that points to the

upstream router as the next hop/default gateway.
