SPI Stateful Packet Inspection (SPI) inspects, and if required blocks packets at the application layer. SPI also maintains TCP and UDP session information, including timeouts and the number of active sessions, and provides the ability to detect and prevent certain types of network attacks such as DoS attacks. Denial of Service (DoS) attacks are aimed at devices and networks with a connection to the Internet. The goal is not to steal information, but to disable a device or network so users no longer have access to network resources. To configure SPI information on your Router: 1 Select Firewall from the main menu, then select the SPI tab to display the SPI screen: Figure 44 SPI Screen Intrusion Detection: Check on the box to enable the Stateful Packet Inspection (SPI), Hacker Pattern detection and Denial of Services(DoS) features to further guard your networks from internet attacks.
