What’s the difference between a stateful and stateless firewall?

 

Stateful Firewall	Stateless Firewall
A stateful firewall can monitor various aspects of traffic streams, their communication channels, and their characteristics.	A stateless firewall does not inspect traffic. It identifies TCP connection stages, packet state, and other updates. Their main focus is to monitor packets only.
It maintains information about connections in a connection table.	It delivers fast performance as it does not care about the traffic load.
Some examples are ASA, Checkpoint, and PIX.	An example of a stateless firewall is File Transfer Protocol (FTP).
