<para>If you do not plan to use traffic shaping for a device, don't put it

in here as it limits the troughput of that device to the limits you set

here.</para>

<listitem>

<para>The incoming <emphasis>bandwidth</emphasis> of that interface.
|
|
Please note that you are not able to do traffic shaping on incoming
|
|
traffic, as the traffic is already received before you could do so.
|
|
But this allows you to define the maximum traffic allowed for this
|
|
interface in total, if the rate is exceeded, the packets are
|
|
dropped. You want this mainly if you have a DSL or Cable connection
|
|
to avoid queuing at your providers side.</para>
|
|
|
|
<para>If you don't want any traffic to be dropped, set this to a
|
|
value to zero in which case Shorewall will not create an ingress
|
|
qdisc.</para>
|
|
|
|
<para>Use <emphasis role="bold">kbit</emphasis> or <emphasis
|
|
role="bold">kbps</emphasis>(for Kilobytes per second) for speed, and
|
|
make sure there is NO space between the number and the unit.</para>

<listitem>

<para>The outgoing <emphasis>bandwidth</emphasis> of that interface.
|
|
This is the maximum speed your connection can handle. It is also the
|
|
speed you can refer as "full" if you define the tc classes. Outgoing
|
|
traffic above this rate will be dropped.</para>
