Deep Packet Inspection (DPI)

Deep Packet Inspection (DPI) enables the identification of application control, and is used for network traffic monitoring. Protocol detection is carried out by the system depending on the current status of the Application Control module.

This setting controls whether Deep Packet Inspection (DPI) is applied to network traffic.

• Enabled: all network traffic passes through DPI, including traffic handled by Firewall rules that do not have an Application Control profile assigned. The system performs protocol detection for all traffic.
• Disabled: DPI-based protocol detection is not performed. Traffic is processed without protocol identification through DPI.
