The FortiDDoS device is designed to protect a system or a network of systems from
rate-based attacks and anomaly attacks. If multiple systems or workgroups are
protected by a FortiDDoS device, a switch will be required between the FortiDDoS
appliance and the protected systems.
Figure 2: A simple network prior to installation of a FortiDDoS device
In a simple network shown in Figure 2 , a system is connected to an Ethernet local area
network.
In the simplest configuration, you can install a FortiDDoS unit as an inline device, as
shown in
Figure 3 .

The appliance is stateful and bidirectional, so a concept of ‘direction’ must be
introduced to differentiate between inbound and outbound traffic.
As shown in Figure 4 below, in a typical installation, the Ethernet segment connected
to the protected systems is connected to LAN 1. The Ethernet segment connected to
the rest of the network (typically the Internet) is connected to WAN 1.
