Place the unit on a stable surface. It requires 1.5 inches (3.75 cm) clearance above and 

on each side to allow for cooling. 

Plug in power cable to the unit before connecting power. 

The Status light flashes while the unit is starting up and turns off when the system is up 

and running.

Connect the FortiGate unit to a power outlet and to the internal and external networks.

Before beginning to configure the FortiGate unit, you need to plan how to integrate the unit into your network. Your configuration plan depends on the operating mode you select: NAT/Route 

mode (the default) or Transparent mode.

In NAT/Route mode, each FortiGate unit is visible to the network that it is connected to. All 

of its interfaces are on 

different subnets. Each 

interface that is connected 

to a network must be 

configured with an IP ad-

dress that is valid for that 

network.

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 configu-

ration, the unit functions as a firewall. Firewall policies control communications through the 

FortiGate unit. No  

traffic can pass through the FortiGate unit until you add firewall policies. In NAT/Route mode, 

firewall policies can operate in NAT mode or in Route mode. In NAT mode, the FortiGate unit 

performs network address translation before IP packets are sent to the destination network. 

In Route mode, no translation takes place.

In Transparent mode, the FortiGate unit is invisible to the network. All of its interfaces are on 

the same subnet. You only have to configure a management IP address so that you can make 

configuration changes. 

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. 

No traffic can pass through the 

FortiGate unit until you add  

firewall policies. 

You can connect up to four network segments to the FortiGate unit to control traffic between                                                 

these network segments.

The FortiGate web-based manager is an easy to use management tool. Use it to configure 

the administrator password, the interface and default gateway addresses, and the DNS 

server addresses.

Requirements: 

An Ethernet connection between the FortiGate unit and management computer. 

Internet Explorer 6.0 or higher on the management computer.

The CLI is a full-featured management tool. Use it to configure the administrator password, 

the interface addresses, the default gateway address, and the DNS server addresses. To 

configure advanced settings, see the Documentation CD-ROM.
