This Handbook assumes you have already installed the appliance into a hardware rack and used the appropriate cables to connect the traffic interfaces to your network.

The FortiDDoS system is deployed inline (between the Internet and your local network resources). Consecutively numbered ports belong to port pairs: Use an odd port numbers (1, 3, 5, and so on) for the LAN-side connection and an even port number (2, 4, 6, and so on) for the WAN-side connection. For example, port1 and port2 are a pair. The port1 interface is connected to a switch that connects servers in the local network; the port2 interface is connected to the network path that receives traffic from the Internet.

For information on hardware appliances, refer to the FortiDDoS hardware manuals.
