The Cisco PIX firewall has several commands in its arsenal to control traffic flow: conduit commands to control traffic from lower security level interfaces to higher security level interfaces; outbound filter commands to control traffic from higher security level interfaces to lower level interfaces; and Cisco Access Control List (ACL) commands.
