Configuring the FortiGate unit

This section provides an overview of the operating modes of the FortiGate unit. 
Before beginning to configure the FortiGate unit, you need to plan how to 
integrate the unit into your network. Your configuration plan depends on the 
operating mode you select: NAT/Route mode or Transparent mode. 

This section includes the following topics: 

•

Planning the FortiGate configuration

•

Preventing the public FortiGate interface from responding to ping requests

•

NAT/Route mode installation

•

Transparent mode installation

Planning the FortiGate configuration

Before you configure the FortiGate unit, you need to plan how to integrate the unit 
into the network. Among other things, you must decide whether you want the unit 
to be visible to the network, which firewall functions you want it to provide, and 
how you want it to control the traffic flowing between its interfaces. 

Your configuration plan depends on the operating mode you select. You can 
configure the FortiGate unit in one of two modes: NAT/Route mode (the default) or 
Transparent mode. 

You can also configure the FortiGate unit and the network it protects using the 
default settings. 

NAT/Route mode

In NAT/Route mode, the FortiGate unit is visible to the network. Like a router, all 
its interfaces are on different subnets. The following interfaces are available in 
NAT/Route mode: 

You can add firewall policies to control whether communications through the 
FortiGate unit operate in NAT or Route mode. Firewall policies control the flow of 
traffic based on the source address, destination address, and service of each 
packet. In NAT mode, the FortiGate unit performs network address translation 
before it sends the packet to the destination network. In Route mode, there is no 
address translation.
