Unfiltered content profile
Use the unfiltered content profile if you do not want to apply content protection to traffic. You can add this content profile to firewall policies for connections between highly trusted or highly secure networks where content does not need to be protected.

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 that you select. The FortiGate unit can be configured in one of two modes: NAT/Route mode (the default) or Transparent mode.
NAT/Route mode
In NAT/Route mode, the 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:
•External is the interface to the external network (usually the Internet).
•Internal is the interface to the internal network.
You can add security policies to control whether communications through the FortiGate unit operate in NAT or Route mode. Security 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 translation.
By default, the FortiGate unit has a NAT mode security policy that allows users on the internal network to securely download content from the external network. No other traffic is possible until you have configured further security policies.
