QuickStart Guide

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 inTransparent 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 straightthrough Ethernet cables to connect the devicesthrough 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
