Each instance of this collection is a collection of firewall programs in a particular state with respect to how they assign attributes to packets. The instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvkVnq5wpEbGdrcN5Y29ycA" class="cyc_term">FirewallTypeByPacketTarget</a> represent features or attributes that a firewall program F assigns to a packet P that determine the fate of P when P arrives at the computer on which F is running. The most common <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvkVnq5wpEbGdrcN5Y29ycA" class="cyc_term">FirewallTypeByPacketTarget</a> are <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rv1415ZwpEbGdrcN5Y29ycA" class="cyc_term">Accept_FirewallTarget</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvprhZ5wpEbGdrcN5Y29ycA" class="cyc_term">Deny_FirewallTarget</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwRD16pwpEbGdrcN5Y29ycA" class="cyc_term">Reject_FirewallTarget</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvtUv7ZwpEbGdrcN5Y29ycA" class="cyc_term">Redirect_FirewallTarget</a>, and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWlRHpwpEbGdrcN5Y29ycA" class="cyc_term">Masquerade_FirewallTarget</a>.

Each instance of this collection is a program designed to filter packets (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvqJ145wpEbGdrcN5Y29ycA" class="cyc_term">Packet_Network</a>) that enter the network or computer that it is protecting. Firewall filtering rules -- usually stored in a coinfiguration file accessed by th program -- describe what the program should do with various kinds of packets -- accepting them and routing them toward their destination, discarding them as though they were never received, or dropping them with a notification sent to the sending machine. Which occurs is determined by whether information in the packet headers satisfies criteria stated in the firewall rules. Any machine that runs a firewall program is a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rv1OM5JwpEbGdrcN5Y29ycA" class="cyc_term">Firewall_Network</a>. firewall program FirewallProgram Redirect-FirewallTarget A <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvkVnq5wpEbGdrcN5Y29ycA" class="cyc_term">FirewallTypeByPacketTarget</a>.
