Ah ok, I found the SYN flood example in the HOWTO.  :)
But that seems to work by dropping packets rather than queueing them,
which is not so good if your bandwidth is very limited (modem dialup).

Because some of the traffic is for this box (doesn't go out) and I
don't want it to ``steal' all the bandwidth from traffic that is
forwarded through the box.  Also, the traffic is mostly asymmetric,
lots of data coming in and only ACKs going out.

Could you post the URL for that?

Hmm, lack of time is a universal problem me thinks...   ;)
