In the following figure, router
R
is connected to the Device’s LAN.
R
connects to two networks,
N1
(192.168.1.x/24) and
N2
(192.168.10.x/24). If you want to send traffic from computer
A
(in
N1
network) to computer
B
(in
N2
network), the traffic is sent to the Device’s WAN default gateway by
default. In this case,
B
will never receive the traffic.
You need to specify a static routing rule on the Device to specify
R
as the router in charge of
forwarding traffic to
N2
. In this case, the Device routes traffic from
A
to
R
and then
R
routes the
traffic to
B
.
This tutorial uses the following example IP settings:

To configure a static route to route traffic from
N1
to
N2
:
1
Log into the Device’s Web Configurator in advanced mode.
2
Click
Network Setting
>
Routing
.
3
Click
Add new Static Route
in the
Static Route
screen.
4
Configure the
Static Route Setup
screen using the following settings:
4a
Select the
Active
check box. Enter the
Route Name
as
R
.
4b
Set
IP Type
to
IPv4
.
4c
Type
192.168.10.0
and subnet mask
255.255.255.0
for the destination,
N2
.
4d
Select
Enable
in the
Use Gateway IP Address field
. Type
192.168.1.253
(
R
’s N1 address)
in the
Gateway IP Address
field.
4e
Select
VDSL/ppp1.1
as the

.
4a
Click
OK
.
Now
B
should be able to receive traffic from
A
. You may need to additionally configure
B
’s firewall
settings to allow specific traffic to pass through.

Let’s say you are a team leader of a small sales branch office. You want to prioritize e-mail traffic
because your task includes sending urgent updates to clients at least twice every hour. You also
upload data files (such as logs and e-mail archives) to the FTP server throughout the day. Your
colleagues use the Internet for research, as well as chat applications for communicating with other
branch offices.
In the following figure, your Internet connection has an upstream transmission bandwidth of
10,000 kbps. For this example, you want to configure QoS so that e-mail traffic gets the highest
priority with at least 5,000 kbps. You can do the following:
Configure a queue to assign the highest priority queue (1) to e-mail traffic going to the WAN
interface, so that e-mail traffic would not get delayed when there is network congestion.
Note the IP address (192.168.1.23 for example) and/or MAC address (AA:FF:AA:FF:AA:FF for
example) of your computer and map it to queue 7.
Note: QoS is applied to traffic flowing out of the Device.
Traffic that does not match this class is assigned a priority queue based on the internal QoS
mapping table on the Device.
QoS Example
1
Click
Network Setting > QoS > General
and select
Enable
. Set your
WAN Managed Upstream
Bandwidth
to 10,000 kbps (or leave this blank to have the Device automatically determine this
figure). Click
Apply
.

Tutorial: Advanced > QoS > Class Setup
Class Name
Give a class name to this traffic, such as
E-mail
in this example.
From
Interface
This is the interface from which the traffic will be coming from. Select
LAN1
for this
example.
Ether Type
Select
IP
to identify the traffic source by its IP address or MAC address.
IP Address
Type the IP address of your computer -
192.168.1.23
. Type the
IP Subnet Mask
if you
know it.
MAC Address
Type the MAC address of your computer -
AA:FF:AA:FF:AA:FF
. Type the
MAC Mask
if you
know it.
To Queue
Index
Link this to an item in the
Network Setting > QoS > Queue Setup
screen, which is the
E-
mail
queue created in this example.
