WAN Configuration 2-25
•
Priority – This is the Quality of Ser vice setting for the rule, based on the TOS bit information. Select
assure , expedite , or off (default) from the pop-up menu. The following table outlines the TOS bit settings
and behavior:
•
Numerical Protocol – If you select “Other” protocol, this field appears for you to provide its actual protocol
number, with a range of 0 – 255.
•
Direction – Choose outbound (default), inbound , or both from the pop-up menu.
•
Start Port – For TCP or UDP protocols, you can optionally specify a range of por ts. Enter the star ting por t
here.
•
End Port – Enter the ending por t here.
•
Inside IP Address/Netmask – For outbound flows, specify an IP address and subnet mask on your LAN. For
inbound flows, this setting is ignored.
•
Outside IP Address/Netmask – If you want traffic destined for and originating from a cer tain WAN IP
address to be controlled, enter the IP address and subnet mask here. If you leave the default all-zeroes,
the outside address check is ignored.
For outbound flows, the outside address is the destination IP address for traffic; for inbound packets, the
outside address is the source IP address.
When you are finished, select COMMIT and press Return. You will be returned to the Diffser v Options screen
and your settings will take effect.
Priority Queuing (TOS bit)
Motorola Netopia® Embedded Software Version 8.7.4 offers the ability to prioritize delay-sensitive data over the
WAN link on DSL connections.
Cer tain types of IP packets, such as voice or multimedia packets, are sensitive to latency introduced by the
network. This means that if such packets are not received rapidly, the quality of ser vice degrades. If you expect
to route significant amounts of such traffic you can configure your router to prioritize this type of traffic using the
priority queuing feature.
To configure your router to prioritize delay-sensitive data, navigate to the Advanced Connection Options screen
in the console menu.
QoS Setting TOS Bit Value Behavior
off TOS=000 This custom rule is disabled. You can activate it by selecting one of
the two settings below. This setting allows you to pre-define flows
without actually activating them.
assure TOS=001 Use normal queuing and throughput rules, but do not drop packets
if possible. Appropriate for applications with no guaranteed deliver y
mechanism.
expedite TOS=101 Use minimum delay. Appropriate for VoIP and video applications.
