When you click Setup, you can configure the bandwidth ratio for QoS of the WAN interface.
There are four queues allowed for QoS control. The first three (Class 1 to Class 3) class rules
can be adjusted for your necessity. Yet, the last one is reserved for the packets which are not
suitable for the user-defined class rules.

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 WAN.
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 factory default for this setting is checked.
Please also define which traffic the QoS Control settings will
apply to.
IN- apply to incoming traffic only.
OUT-apply to outgoing traffic only.
BOTH- apply to both incoming and outgoing traffic.
Check this box and click OK, then click Setup link again. You

For example, if your ADSL supports 1M of downstream and
256K upstream, please set 1000kbps for this box. The default
value is 10000kbps.

Check this and set the limited bandwidth ratio on the right
field. This is a protection of TCP application traffic since
