Web-based Manager
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.

Collecting Information
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.
Refer to the Tools and Documentation CD 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).
Upgrading to High Encryption
This FortiGate unit has a factory installed low encryption feature set. You can purchase a high encryption upgrade within 90 days of shipment from Fortinet. Fortinet Technical Support can
provide a high encryption license key once you have provided suitable documentation that the necessary export licenses have been granted for your region, and our legal department has
authorized the use of high encryption.
When you receive the high encryption license key, in the CLI, enter the command exec crypto-license <high-enc-key>.
Fortinet does not guarantee that the customer will receive a export license upon purchase of the product or license key.
