      I have to say that altq is not well documented and I cant seem to find answers for the two questions below, was hoping someone here could help.

      1. M0n0wall's dummynet use a mask to create separate flows (dynamic queues) inside a queue. Does altq have a similar feature?

      2. When shaping uploads by ip address. are the packets NAT'd before the filter policy sees them? If so, does that mean I can't shape uploads by internal ip addresses?

        Nope.  We've had some problems integrating dummynet, this may appear in the future.

        Correct.  NAT occurs before filter policy (which is what classifies traffic).  There are alternatives, but we're not geared up to use them (and using them isn't terribly scalable at this time).

          OK.. policy filtering works fine. just wanted to be sure that if NAT was enabled that the packets were translated before (NAT always sees the packet first right?). I wouldnt worry about alternatives to something that aint broken, and its not limiting in any way as far as I can see.
