A default gateway is required for the FortiGate unit to route connections to the Internet.

Configuring

NAT/Route mode
You would typically use NAT/Route mode when the FortiGate unit is deployed as a gateway between
private and public networks. In its default NAT/Route mode configuration, the unit functions as a firewall.
Firewall policies control communications through the FortiGate unit.
Transparent mode
You would typically use the FortiGate unit in Transparent mode on a private network behind an existing
firewall or behind a router. In its default Transparent mode configuration, the unit functions as a firewall.
Web-based Manager
1. Connect the FortiGate MGMT1 interface to a management computer Ethernet interface. Use a cross-
over Ethernet cable to connect the devices directly. Use straight-through Ethernet cables to connect
the devices through a hub or switch.
2. Configure the management computer to be on the same subnet as the MGMT1 interface of the
FortiGate unit. To do this, change the IP address of the management computer to 192.168.1.2 and
the netmask to 255.255.255.0.
3. To access the FortiGate web-based manager, start a web browser and type the address
http://192.168.1.99
4. Type admin in the Name field and click Login.

Command Line Interface
1. Use the RJ-45 to DB9 serial cable to connect the FortiGate Console port to the management com-
puter serial port.
2. Start a terminal emulation program (HyperTerminal) on the management computer. Use these set-
tings: Baud Rate (bps) 9600, Data bits 8, Parity None, Stop bits 1, and Flow Control None.
3. At the Login: prompt, type admin and press Enter twice (no password required).
NAT/Route mode
1. Configure the FortiGate MGMT1 interface.
config system interface
edit MGMT1
set ip <intf_ip>/<netmask_ip>
end
2. Repeat to configure each interface, for example, to configure the Port 1 interface.
config system interface
edit port1
...
3. Configure the primary and secondary DNS server IP addresses.
config system dns
set primary <dns-server_ip>
set secondary <dns-server_ip>
end
4. Configure the default gateway.
config router static
edit 1
set gateway <gateway_ip>
end
Transparent Mode
1. Change from NAT/Route mode to Transparent mode and configure the Management IP address.
config system settings
set opmode transparent
set manageip <mng_ip>/<netmask>
set gateway <gateway_ip>
end
2. Configure the DNS server IP address.
config system dns
set primary <dns-server_ip>
set secondary <dns-server_ip>
end
