Firewall Stateful Inspection Table
The Firewall Stateful Inspection table is a sophisticated, scripted stateful firewall and route inspection
engine. Stateful inspection is a powerful tool allowing the router to keep track of a TCP/UDP or ICMP
session and match packets based on the state of the connection on which they are being carried.
The table contains a list of dynamic firewall rules that have been created when packets have matched
a configured firewall with the inspect-state keyword specified. See the [inspect-state] keyword
description for more information on stateful inspection.
