What's a stateful firewall?


Modern firewalls inspect network traffic in what is called a 'stateful' manner. This means that for each conversation a computer begins with another computer, the firewall will keep track of the 'state' of that conversation. Because of this knowledge, the firewall is capable of making changes to the way it handles traffic at each stage of a conversation. In practice, this typically means that we don't need to explicitly allow the network traffic that will occur as a response.
