<para>Entries in this file define the bandwidth for interfaces on which
|
|
you want traffic shaping to be enabled.</para>
|
|
|
|
<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>Name of interface. Each interface may be listed only once in
|
|
this file. You may NOT specify the name of an alias (e.g., eth0:0)
|
|
here; see http://www.shorewall.net/FAQ.htm#faq18</para>
|
|
|
|
<para>You man NOT specify wildcards here, e.g. if you have multiple
|
|
ppp interfaces, you need to put them all in here!</para>
|
|
|
|
<para>If the device doesn't exist, a warning message will be issued
|
|
during "shorewall [re]start" and "shorewall refresh" and traffic
|
|
shaping configuration will be skipped for that device.</para>

|
|
|
|
<listitem>
|
|
<para>The incoming Bandwidth 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 kbit or kbps(for Kilobytes per second) for speed, and make
|
|
sure there is NO space between the number and the unit.</para>

<term><emphasis role="bold">OUT-BANDWIDTH</emphasis></term>

<listitem>
|
|
<para>The outgoing Bandwidth of that interface. This is the maximum
|
|
speed you 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>
