Aaron, Visit the kernel packet traveling diagram linked from http://www.docum.org/. This may answer your question. If not, then explain to us what you are using each of the tools for. It sounds like you are using iptables -t nat -j MASQUERADE (or something like that; maybe SNAT?) iptables -t mangle ??? (what are you doing with mangle) tc : As I try to solve my problems with iptables, nat and traffic shaping (with : ip accounting thrown intot he mix) a friend of mine just sent this claim. : Is it true? Will I have to step back to ipchains, or is there a way to : force packets through the traffic shaping filters using iptables? Without knowing what exactly you are trying to do, we can't answer your question, and certainly can't comment on the veracity of your friend's statement. As a general guideline though, if you can think of a way to do something with ipchains, you can probably do something similar with iptables (and usually it's easier with iptables). : > If you are using iptables, you MUST forget it, or change to : > ipchains, because masq is done by nat table, and shaping is done by : > mangle table. I cannot found any way to drive the packet 1. thru : > nat, than mangle, instead of using OUTPUT and FORWARD. Good luck, -Martin -- Martin A.
