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.
