<para>flow=<emphasis>keys</emphasis> - Shorewall attaches an SFQ
queuing discipline to each leaf HTB class. SFQ ensures that each
<firstterm>flow</firstterm> gets equal access to the interface.
The default definition of a flow corresponds roughly to a
Netfilter connection. So if one internal system is running
queuing discipline to each leaf HTB and HFSC class. SFQ ensures
that each <firstterm>flow</firstterm> gets equal access to the
interface. The default definition of a flow corresponds roughly
to a Netfilter connection. So if one internal system is running
BitTorrent, for example, it can have lots of 'flows' and can
thus take up a larger share of the bandwidth than a system
having only a single active connection. The
<option>flow</option> classifier (module cls_flow) works around
this by letting you define what a 'flow' is. The clasifier must
be used carefully or it can block off all traffic on an
interface! The flow option can be specified for an HTB leaf
class (one that has no sub-classes). We recommend that you use
the following:</para>
