In the following figure, router

R

is connected to the VMG’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 VMG’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 VMG to specify

R

as the router in charge of

forwarding traffic to

N2

. In this case, the VMG 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 VMG’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

’s N1 address)

in the

Now

B

should be able to receive traffic from

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 VMG.

Traffic that does not match this class is assigned a priority queue based on the internal QoS

mapping table on the VMG.

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 VMG automatically determine this

figure). Click

Apply

.
