Basic Inline deployment
FortiDDoS is state-aware and bidirectional. The data packet traffic is described as either incoming (inbound) and/or outgoing (outbound).
FortiDDoS may be installed in asymmetric traffic situations where it sees only the inbound traffic for some TCP sessions or UDP flows and only the outbound traffic for others. The settings must be configured for this mode.
The figure below shows a basic inline deployment. The FortiDDoS-F appliance is positioned ‘inline’, meaning it is installed between the Internet and the protected network.
