Stateful Packet Inspection (SPI) is a firewall architecture that works at the network layer.
Unlike legacy static packet filtering, which examines a packet based on the information in its
header, stateful inspection builds up a state machine to track each connection traversing all
interfaces of the firewall and makes sure they are valid. The stateful firewall of Vigor router
not just examine the header information also monitor the state of the connection.
The purpose of this is to enable the SPI firewall for the filtering incoming packets and
outgoing packets. Simply check the box and click OK.
