Connecting

•

•

•

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

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.

Planning the Configuration

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.

NAT/Route mode 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

Internal

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 configuration, 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,

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

Internal network configuration changes.

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.

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.

Refer to the Documentation CD-ROM for information on how to control traffic, and how to configure HA, antivirus protection, FortiGuard, Web content filtering, Spam filtering, intrusion prevention (IPS), and virtual private networking (VPN).

Choosing a Configuration Tool

Web-based manager

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.

Command Line Interface (CLI)

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.

•

•

Requirements:

The DB-9 serial connection between the FortiGate unit and management computer.

A terminal emulation application (HyperTerminal for Windows) on the management computer.

4.

Connect the FortiGate internal 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.

Configure the management computer to be on the same subnet as the internal 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.

To access the FortiGate web-based manager, start Internet Explorer and browse to https://192.168.1.99 (remember to include the “s” in https://).

Type admin in the Name field and select Login.
