<para>Said another way, reading just Shorewall documentation is probably
not going to give you enough background to use this material. Shorewall
may make iptables easy but the Shorewall team simply can't be expected to
spoon-feed Linux traffic control to you (please remember that the user's

<title>Using builtin traffic shaping/control</title>
<para>Shorewall's builtin traffic shaping feature provides a thin layer on
top of the ingress qdesc, HTB and SFQ. That translation layer allows you

<para>Those few features are really all that builtin traffic
shaping/control provides; consequently, you need to understand HTB and
Linux traffic shaping as well as Netfilter packet marking in order to use
the facility. Again, please see the links at top of this article.</para>
