Fortinet 310B User Manual

In Transparent mode, the FortiGate unit is invisible to the network. Similar to a 
network bridge, all FortiGate interfaces must be on the same subnet. You only 
have to configure a management IP address to make configuration changes. The 
management IP address is also used for antivirus and attack definition updates.

You typically use the FortiGate unit in Transparent mode on a private network 
behind an existing firewall or behind a router. The FortiGate unit performs firewall 
functions, IPSec VPN, virus scanning, IPS web filtering, and Spam filtering. 

To configure, maintain and administer the FortiGate unit, you need to connect to 
it. There are two methods for these tasks:

• using the web-based manger, a GUI interface using a current web browser 

such as FireFox or Internet Explorer.

• using the command line interface (CLI), a command line interface similar to 

DOS or UNIX commands using an SSH terminal or Telnet terminal.

To connect to the web-based manager, you require: 

• a computer with an Ethernet connection
• Microsoft Internet Explorer version 6.0 or higher or any recent version of the 

most popular web browser

• an Ethernet cable.

Set the IP address of the management computer to the static IP address 
192.168.1.2 with a netmask of 255.255.255.0.

Using the Ethernet cable, connect the internal interface of the FortiGate unit to the 
computer Ethernet connection. 

Start your browser and enter the address https://192.168.1.99. (remember to 
include the “s” in https://).
