Stateful vs stateless firewall needs for enterprise For larger enterprises, stateful firewalls are the better choice. Because they offer dynamic packet filtering, they can adapt to a variety of threats using data gathered from previous network activity to ascertain the danger level of novel threats....
making sure they are all legitimate. Network-based static packet filtering also examines network connections, but only as they come in, focusing on the data in the packets’ headers. This data provides less information to the firewall, limiting it to where it came from and where it is going...
While the requirements for efficiency led to the design of ever more complex systems, evolving from stateless to stateful firewalls, this complexity induced new vulnerabilities. In this paper, we discuss a new vulnerability present in Packet Filtering that we called Vulnerability on Firewall States (...

Note that connections have a timeout value, so iptables may “forget” some long idle connection and begin dropping packets.Originally packet filters were stateless, and had to decide what to do with a packet only by examining that packet’s layer 3 (IP, ICMP) and 4 (TCP, UDP) headers....
filtering for each IPv4 destination address, etc.). The tunneling methods do not have such an advantage, without any deep packet inspection for processing the inner IPv4 packet of the tunnel packet. 2. If the ISP for end users can assign an IPv6 prefix greater than ...
