How to get all ACK packets into a high priority queue?

[GomezAddams]

I want to use pfsense to "fix" the buffer bloat that my 3mb/385kb DSL suffers. I've tried using the traffic shaping wizard, but I can't seem to get quite what I want.

The wizard seems to offer a way to make any given sort of tcp traffic and the associated acks go to a given queue, but I don't really want that. Other than VoIP, I don't care about priorities of upstream traffic, but I DO want ALL upstream acks to get higher priority than everything else (other than VoIP).

Using the rules that the wizard generates, upstream heading acks from default downstream heading traffic hits the default queue. I want it in the qACK queue.

Is it as simple as creating a floating rule at the end of the rules that matches every tcp packet and sends it to the qACK/qDefault queues?

What I want is:

1. Top priority: VoIP both directions
2. Medium priority: ACK packets without data heading upstream
3. Everything else

I know how to get #1 and #3, but #2 eludes me. I figure I need a rule, but the rules documentation is a bit sparse

Yes, on interface WAN, direction OUT (considering that you want all your TCP traffic on the qDefault queue and no further classification)
