Table10 on page 45 to complete the following procedure. Starting with Main Menu
displayed on the LCD, use the front control buttons and LCD:
1Press Enter three times to configure the PORT1 IP
address.
2Set the PORT1 IP address.
Use the up and down arrow keys to increase or decrease the value of each IP address
digit. Press Enter to move to the next digit. Press Esc to move to the previous digit.
3When you have set the last digit of the IP address, press Enter.
4Use the down arrow to highlight Netmask.
5Press Enter and set the internal Netmask.
6When you have set the last digit of the Netmask, press Enter.
7Press Esc to return to the Main Menu.
8Repeat these steps to configure PORT2, the PORT2 default gateway, PORT3, and
PORT4/HA if required.
You have now completed the basic configuration of your FortiGate unit, and you can
proceed to “Completing the configuration” on page 50.
Using the command line interface
As an alternative to using the setup wizard, you can configure the FortiGate unit using
the command line interface (CLI). To connect to the CLI, see “Connecting to the
command line interface (CLI)” on page 33.

Configuring the FortiGate unit to operate in NAT/Route mode

Use the information that you gathered in Table10 on page 45 to complete the
following procedures.

Configuring NAT/Route mode IP addresses

1Log into the CLI if you are not already logged in.
2Set the IP address and netmask of interface 1 to the internal IP address and netmask
that you recorded in Table10 on page 45. Enter:
set system interface port1 mode static ip <IP_address>
<netmask>
Example
set system interface port1 mode static ip 192.168.1.1
255.255.255.0
Note: When you enter an IP address, the LCD display always shows three digits for each part
of the address. For example, the IP address 192.168.100.1 appears on the LCD display as
192.168.100.001. The IP address 192.168.23.45 appears as 192.168.023.045.
