Abstract
A system, method, and computer program product for controlling data through a firewall which may be dynamically configurable. The method may comprise defining at least one node, wherein the at least one node is associated with two or more network interfaces; associating a set of firewall rules with the at least one node; receiving a packet at a first node of the at least one node; and accepting or denying the packet based on the set of firewall rules. The firewall rules include dynamic chains of rules having defined places where firewall rules may be dynamically inserted into or deleted from the firewall while the firewall is operating on one or more machines connected to network segments where the nodes reside.
