Stateful inspection firewalls overcome the limitations of packet filter firewalls and application proxy servers. They examine more than just the "to" and "from" addresses in the data packets, and do not require a proxy for every application being accessed. Stateful inspection firewalls determine whether packets can get through the firewall based on the protocol, port, and source and destination addresses. For every request that is allowed by this strategy, stateful inspection firewalls open up a limited time window to allow response packets, but ONLY from the same host. Also, by maintaining information about previous packets, stateful inspection firewalls can quickly verify that packets meet the criteria for authorized traffic, making them inherently fast.
