Hello,
I am doing some researchs about stateful firewalls for my studies.
Stateful firewalls maintain state tables based on the the state of the connection. In the case of netfilter, state is known as NEW, ESTABLISHED, RELATED or INVALID. But I could also see that state is more generally parameters from the connection such as (source/destination addresses, source destination ports, and sequence number). Is the NEW, ESTABLISHED…, the only use of netfilter or is it really the general vocabulary used for all stateful firewalls? What about Iptable??
Thank you
Lili
