<note>
|
|
<para>Simple traffic shaping is only useful on interfaces where
|

queuing occurs. As a consequence, internal interfaces seldom

benefit from simple traffic shaping. VPN interfaces are an
|
|
exception because the encapsulated packets are later transferred
|
|
over a slower external link.</para>

<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.Must be set to zero if the REDIRECTED INTERFACES column is
|
|
non-empty.</para>
|
|
|
|
<para>The optional burst option was added in Shorewall 4.4.18. The
|
|
default <replaceable>burst</replaceable> is 10kb. A larger
|
|
<replaceable>burst</replaceable> can help make the
|
|
<replaceable>bandwidth</replaceable> more accurate; often for fast
|
|
lines, the enforced rate is well below the specified
|
|
<replaceable>bandwidth</replaceable>.</para>
|
|
|
|
<para>What is described above creates a rate/burst policing filter.
|
|
Beginning with Shorewall 4.4.25, a rate-estimated policing filter
|
|
may be configured instead. Rate-estimated filters should be used
|
|
with ethernet adapters that have Generic Receive Offload enabled by
|
|
default. See <ulink
|
|
url="http://www.shorewall.net/FAQ.htm#faq97a">Shorewall FAQ
|
|
97a</ulink>.</para>
|
|
|
|
<para>To create a rate-estimated filter, precede the bandwidth with
|
|
a tilde ("~"). The optional interval and decay_interval determine
|
|
how often the rate is estimated and how many samples are retained
|
|
for estimating. Please see <ulink
