Section 4 - Advanced
QoS Engine Rules:
A QoS Engine Rule identifies a specific message flow
and assigns a priority to that flow. For most applications,
automatic classification will be adequate, and specific QoS
Engine Rules will not be required.
The QoS Engine supports overlaps between rules, where
more than one rule can match for a specific message flow.
If more than one rule is found to match the rule with the
highest priority will be used.
Local IP: The rule applies to a flow of messages whose LAN-side IP
address falls within the range set here.
Local Port: The rule applies to a flow of messages whose LAN-side port
number is within the range set here.
Remote IP:
The rule applies to a flow of messages whose WAN-side IP
address falls within the range set here.
Remote Port: The rule applies to a flow of messages whose WAN-side port
number is within the range set here.
Priority:
The priority of the message flow is entered here -- 1 receives
the highest priority (most urgent) and 255 receives the
lowest priority (least urgent).
Schedule: Choose a schedule for the QoS rule.
