I'm new to this list, but not exactly to iproute stuff.
I'd like to solve a specific problem with bandwidth coming from different external sources towards the internal network (also the other way around, but I figure that's not so much a problem, since that is egress traffic shaping).
The network looks like this:
internet ------ ISP-------[shaping/router] | | +- net1 -------- host1 mirrors host2 +- net2
in text: we connect to the internet via an ISP, where we also have an externally accessible host (host2). Internally we use NAT and several subnets.
We have a 100Mbit/s connection to the ISP, but we only pay for 1Mbit/s. So in order to keep our traffic within the agreed parameters, we need to police our incoming and outgoing traffic. However the traffic from and to the ISP and host2 doesn't have to be policed.
For our external traffic there's not much problem to shape the traffic in the egress queues (using HTB and TBF/SFQ stuff). This is well described in the LARTC howto documentation.
My problem is with the incoming traffic. The examples in the howto don't go very much into this and from what I understand the ingress queue is much less advanced than the egress queue. I read something about an intermediate queue, but I don't understand how that works (yet).
My question is whether this is something I can do using the ingress queue, somehow defining filter rules with different queue associated with that, or whether someone has experience with a similar configuration.
If this is not possible, I might be able to solve it differently by adding another host with just 2 interfaces and using only egress queues, but I'd prefer limiting my solution to a single host.
Thanks in advance
Simon
PS, if this is the second time you get this message, I was too impatient and sent the first one before my confirmation was in....
