I was hoping (of course) that IFB would be able to do this for me, but it doesn't seem to want to play nicely. Am I missing something? All suggestions and comments very much appreciated! :-)
I think IFB should do here, Andrew already mentioned IMQ, but for normal setups the only real need for that would be if you need to shape traffic destined for the router as well as forwarded and then only if you have to nat onto a single public address. Your setup seems to be just forwarding so that doesn't apply. You should be able to use ifb to catch traffic leaving on the lan facing egress devices. Having previously marked using iptables depending on dst if or mark with tc. To use filters to redirect from both br0 and wl1 to a single ifb you will need to add eg, a prio qdisc to br0 and wl1 (just because you can't add filters to a device without a "real" qdisc on it, the default pfifo_fast will not do). One other thing to remember is that shaping traffic coming in from wan is not the same as shaping that going out - you are at the wrong end of the bottleneck and have to back off/sacrifice some bandwidth or you will never build up a queue to do anything with. How much to back off somewhat depends on the speed of the link and how much you care about latency and how hard you hit the line eg shaping a few tcps is easier than a few hundred from torrents. -- To unsubscribe from this list: send the line "unsubscribe lartc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
