Abstract
A method is provided for implementing a firewall in a firewall architecture. The firewall architecture includes a plurality of network layers and a first firewall engine. The layers send packets and packet information to the first firewall engine, maintain and pass packet context to subsequent layers, and process the packets. The first firewall engine compares the packet information to one or more installed filters and returns an action to the layers indicating how to treat the packet.
