First, we’ll define general options available in all IURs, including Traffic Flow Rule Sets
(TFRS). Second, we’ll list the default IURs and the associated policies. Third, we’ll give an
example on how to customize IURs and other advanced policies.
Traffic Flow Rule Sets
Click on Manage -> Policies & Rules -> Internet Usage Rules -> Default Usage Rules. This
screen will present the options available under Add/Edit Internet Usage Rule Sets. Towards
the top will be posted the Rule Set Name and Rule Set Description followed by the Traffic
Flow Rule Set Drop-Down Box. For you to correctly control and filter web traffic, you will
need to understand Traffic Flow Rule Sets.
Traffic Flow Rule Sets (TFRS) are the basic traffic identification and control engine within
Optinet. TFRS allow you to dictate how traffic will be identified, controlled, reported,
filtered, and shaped. TFRS define the content rules and implement restrictions on identified
traffic for users on the network. In essence, TFRS are the controlling mechanisms that
decide what types of traffic are allowed and what types are not. TFRS will be your tool in
managing network traffic and reporting on such.
Select the Traffic Flow Rule Sets Drop-Down Box to view the default TFRS. These are also
listed below with their corresponding targets.
