Configuring Static Route for Routing to Another

Network

In order to extend your Intranet and control traffic flowing directions, you may connect a router to

the Device’s LAN. The router may be used to separate two department networks. This tutorial

shows how to configure a static routing rule for two network routings.

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

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:

:

1

Log into the Device’s Web Configurator in advanced mode.

Configuring QoS Queue and Class Setup

This section contains tutorials on how you can configure the QoS screen.

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.
