Consider:

Internet -> Router -> Eth1 -> br0 -> Eth0 -> local net

Now by applying QOS to eth1 I control outgoing traffic from everywhere.
By applying QOS to eth0 I control incoming to the localnet (great), but
NOT to the local bridge machine

Now I could fix this by using the IMQ device on eth1 and grabbing
incoming traffic, but the top of the file at
http://digriz.org.uk/jdg-qos-script/ implies that it is possible to do
this without IMQ...

The question is how? I don't see how to do it.... What am I missing?



It's my understanding that you cannot attach much of anything except the police filter on the ingress hook. As such, you need IMQ to attach egress qdiscs to for application to incoming traffic, as you would to the root hook for egress traffic.

Sure, that's my understanding as well, but see the comments at the top of the script, and also the way the script carefully checks for a bridge connection and avoids using the IMQ device...


Perhaps it's just a mistaken comment, but it implies that he thinks it's possible to avoid using the IMQ device... I can't see how though (I did drop him an email, but no answer so far)

THanks for any ideas on this conundrum
