Fortinet FORTIGATE-50B Instrução De Instalação

This section provides an overview of the operating modes of the FortiGate unit, 
NAT/Route and Transparent, and how to configure the FortiGate unit for each 
mode. There are two ways you can configure the FortiGate unit, using the 
web-based manager or the command line interface (CLI). This section will step 
through using both methods. Use whichever you are most comfortable with.

The FortiGate unit can run in two different modes, depending on your network 
infrastructure and requirements. You have a choice between NAT/Route mode 
and Transparent mode. Both include the same robust network security features 
such as antispam, antivirus, VPN and firewall policies.

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

In NAT mode, each port is on a different subnet, enabling you to have a single IP 
address available to the public Internet. The FortiGate unit performs network 
address translation before it sends and receives the packet to the destination 
network.

In Route mode, there is no address translation.

You typically use NAT/Route mode when the FortiGate unit is operating as a 
gateway between private and public networks. In this configuration, you would 
create NAT mode firewall policies to control traffic flowing between the internal, 
private network and the external, public network, usually the Internet.
