Preparing to configure the FortiGate unit in NAT/Route mode

Use 

Table 10 on page 31

 to gather the information you need to customize 

NAT/Route mode settings. 

You can configure the FortiGate unit in several ways: 

• The web-based manager GUI is a complete interface for configuring most 

settings. See 

“Using the web-based manager” on page 32

• The front control buttons and LCD is an optional interface for configuring IP 

addresses, default gateways, and the operating mode. See 

“Using the front 

control buttons and LCD” on page 19

.

• The command line interface (CLI) is a complete text-based interface for 

configuring all settings. See 

“Using the command line interface” on page 35

.

The method you choose depends on the complexity of the configuration, access 
and equipment, and the type of interface you are most comfortable using.

A default route consists of a default gateway and the name of the 

interface connected to the external network (usually the Internet). 

The default gateway directs all non-local traffic to this interface and 

to the external network.
