Intrusion Detection When the SPI (Stateful Packet Inspection) firewall feature is enabled, all packets can be blocked.  Stateful Packet Inspection (SPI) allows full support of different application types that are using dynamic port numbers.  For the applications checked in the list below, the Device will support full operation as initiated from the local LAN. The Device firewall can block common hacker attacks, including IP Spoofing, Land Attack, Ping of Death, IP with zero length, Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding.
