WAN Inbound Bandwidth It allows you to set the connecting rate of data input for WAN.
WAN Outbound Bandwidth It allows you to set the connecting rate of data output for
Note: The rate of outbound/inbound must be smaller than the real bandwidth to ensure
correct calculation of QoS. It is suggested to set the bandwidth value for inbound/outbound
as 80% - 85% of physical network speed provided by ISP to maximize the QoS
performance.
Reserved Bandwidth Ratio It is reserved for the group index in the form of ratio of

The first three (Class 1 to Class 3) class rules can be adjusted for your necessity. To add, edit
or delete the class rule, please click the Edit link of that one.
After you click the Edit link, you will see the following page. Now you can define the name

Check this and set the limited bandwidth ratio on the right
field. This is a protection of TCP application traffic since
UDP application traffic such as streaming video will exhaust
lots of bandwidth.
For the download speed might be impacted by the uploading

faster to speed the network traffic.
The ratio typed here is reserved for limited bandwidth of UDP
application.
