These may help: http://xkr47.outerspace.dyndns.org/netfilter/packet_flow/ http://xkr47.outerspace.dyndns.org/netfilter/packet_flow/packet_flow9.png http://ebtables.sourceforge.net/br_fw_ia/PacketFlow.png You might also want to hit up TLDP.org and you local manpages. Iptables is somewhat complex, but it is probably also one of the best documented sections of Linux administration. I can't help you with guarddog. I write my iptables rules by hand so they remain understandable. I can't stand the trash that most iptables rules generators produce.
