Might be "an easy thing", but I don't know how!

Perhaps the following will help.

http://andthatsjazz.org/lartc/ultimate.html shows a 4-queue Wonder
script.

Jim diGriz's URL is not working right now; traceroute dies at
213.162.127.69.  But it is a "don't miss", so keep trying!

What I'm not finding but expect might be possible is a second "root":
tc qdisc add dev eth0 root handle 1: htb default 30
tc qdisc add dev eth0 root handle #: htb default ## << will this work?
Dunno, but I do know that you'll get bad results if the DSL and the
internal network are in the same class.

Wonder forces EVERYTHING not otherwise filtered into the default / bulk
class.  You might want NOT to do that so that unmatched stuff is totally
ignored by HTB.  Rather than "match ip dst 0.0.0.0/0 flowid 1:30" you
add a bunch of filters that match internet but not internal NW...???
