- In computing, a stateful firewall is a network firewall that tracks the operating state and characteristics of network connections traversing it. The firewall is configured to distinguish legitimate network packets for different types of connections. Only packets matching a known active connection are allowed to pass the firewall. In contrast, a stateless firewall does not take context into account when determining whether to allow or block packets.
Stateful packet inspection (SPI), also referred to as dynamic packet filtering, is a security feature often included in business networks.
