<para>This configuration was inspired by the one in this thread on the
|
|
|
|
|
OpenWRT Forum: <ulink

|
|
url="https://forum.openwrt.org/viewtopic.php?pid=154533#p154533">https://forum.openwrt.org/viewtopic.php?pid=154533#p154533</ulink>.

The configuration has been adapted to Shorewall 4.5.6 with the following
|
|
|
|
|
changes:</para>
|

|
|
|
|
|
<orderedlist>
|
|
|
|
|
<listitem>
|
|
|
|
|
<para>The configuration uses an IFB, yet only uses firewall marks in
|
|
|
|
|
the OUTPUT and FORWARD chains to classify packets; clearly that
|
|
|
|
|
doesn't work<footnote>
|
|
|
|
|
<para>To be more precise, it doesn't work with an unpatched
|
|
|
|
|
kernel. The OpenWRT script assumes an 'act_conntrack' patch which
|
|
|
|
|
performs conntrack processing on packets before they are sent to
|
|
|
|
|
the IFB. That patch is not generally available.</para>
|
|
|
|
|
</footnote>The configuration presented here uses U32 classifiers
|
|
|
|
|
(shorewall-tcfilters(5)) to classify traffic for download shaping and
|
|
|
|
|
uses the POSTROUTING chain for upload shaping.</para>

</listitem>
|
|
|
|
|
|
|
|
|
|
<listitem>
|
|
|
|
|
<para>The sample uses a weak form of P2P classification; the one
|
|
|
|
|
presented below uses <ulink url="IPP2P.html">IPP2P</ulink>.</para>

|

|

<listitem>
|
|
|
|

<para>The OpenWRT script assumed that the uplink was ATM -- the one
|
|
|
|
|
below makes no assumption (it specifies 'ethernet' with overhead
|
|
|
|
|
'0').</para>
