1 Change the system to operate in Transparent Mode.
set system opmode transparent
2 Add the Management IP address and Netmask.
set system management ip 192.168.1.1 255.255.255.0
3 Add the default route to the external network.
set system route number 1 gw1 192.168.1.2
Example static route to an external destination
Figure 8 shows a FortiGate unit that requires routes to the FDN located on the
external network. The Fortigate unit does not require routes to the DNS servers or
management computer because they are located on the internal network.
To connect to the FDN, you would typically enter a single default route to the external
network. However, to provide an extra degree of security, you could enter static routes
to a specific FortiResponse server in addition to a default route to the external
network. If the static route becomes unavailable (perhaps because the IP address of
the FortiResponse server changes) the FortiGate unit will still be able to receive
antivirus and NIDS updates from the FDN using the default route.
