Adding a htb qdisc to a class is useless and will only add extra delays.

If you upload, the packets are entering the box with destination address the
ip-address of your box. I'm not sure when the packet gets demasqued but when
this happens AFTER the marking, your packets have not the dst address of your
host so they are not marked and they end up in the default class.
An other question. Is this is a test setup to see if imq is working?
