Connector Type Speed Protocol Description
Internal RJ-45 10/100 Base-T Ethernet Connection to the internal network.
External RJ-45 10/100 Base-T Ethernet Connection to the internet.
DMZ RJ-45 10/100 Base-T Ethernet Optional connection to a DMZ network, or to other 
FortiGate-200 units for high availability. For details, 
see the Documentation CD-ROM. 
Console DB-9  9600 Bps RS-232 Optional connection to the management computer. 
Provides access to the command line interface 
(CLI). 
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 unit before connecting power. 
The Status light ashes 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 congure the FortiGate unit, you need to plan how to integrate the unit into your network. Your conguration plan depends on the operating mode you select: NAT/Route 
mode (the default) or Transparent mode.
NAT/Route 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 
congured with an IP 
address 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 
conguration, the unit 
functions as a rewall. 
Firewall policies control 
communications through 
the FortiGate unit. No trafc can pass through the FortiGate unit until you add rewall poli-
cies. In NAT/Route mode, rewall 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.
Transparent mode
In Transparent mode, the FortiGate unit is invisible to the network. All of its interfaces are on 
the same subnet. You only have to congure a management IP address so that you can make 
conguration changes. 
You would typically use the  
FortiGate unit in Transparent 
mode on a private network 
behind an existing rewall or 
behind a router. In its default 
Transparent mode conguration, 
the unit functions as a rewall. 
No trafc can pass through the 
FortiGate unit until you add 
rewall policies. 
You can connect up to four network segments to the FortiGate unit to control trafc between 
these network segments.
Refer to the Documentation CD-ROM for information on how to control trafc, and how to congure HA, antivirus protection, FortiGuard, Web content ltering, Spam ltering, 
intrusion prevention (IPS), and virtual private networking (VPN).
