Configuring QoS Queue and Class Setup

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

Note: Voice traffic will not be affected by the user-defined QoS settings on the ZyXEL

Device. It always gets the highest priority.

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 (7) to e-mail traffic from

the LAN 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 ZyXEL Device.

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

internal QoS mapping table on the ZyXEL Device.

QoS Example

1

Click

Network Setting > QoS > General

and check

Active

. Set your

WAN

Managed Upstream Bandwidth

to 10,000 kbps (or leave this blank to have the

ZyXEL Device automatically determine this figure). Click

Apply

to save your

settings.

Go to

Network Setting > QoS > Queue Setup

. Click

Add new Queue

to create

a new queue. In the screen that opens, check

Active

and enter or select the

following values, then click

Apply

.

Email

queue created in

this example.

This maps e-mail traffic to queue 7 created in the previous screen (see the

IP

Protocol

field). This also maps your computer’s IP address and MAC address to

queue 7 (see the

Source

fields).

4

Verify that the queue setup works by checking

Network Setting > QoS >

Monitor

. This shows the bandwidth allotted to e-mail traffic compared to other

network traffic.

Access the ZyXEL Device Using DDNS

If you connect your ZyXEL Device to the Internet and it uses a dynamic WAN IP

address, it is inconvenient for you to manage the device from the Internet. The

From Interface

This is the interface from which the traffic will be

coming from. Select

Lan

.

Ether Type

Select

IP

to identify the traffic source by its IP

address or MAC address.

MAC Address

Type the MAC address of your computer -

AA:FF:AA:FF:AA:FF

. Type the

MAC Mask

if you

know it.

IP Address

Type the IP address of your computer -

192.168.1.23

. Type the

IP Subnet Mask

if you

know it.

ZyXEL Device’s WAN IP address changes dynamically. Dynamic DNS (DDNS)

allows you to access the ZyXEL Device using a domain name.

To use this feature, you have to apply for DDNS service at www.dyndns.org.

This tutorial shows you how to:

•

Registering a DDNS Account on www.dyndns.org

•

Configuring DDNS on Your ZyXEL Device

•

Testing the DDNS Setting

Note: If you have a private WAN IP address, then you cannot use DDNS.

3.12.1

Registering a DDNS Account on www.dyndns.org

1

Open a browser and type

.

2

Apply for a user account. This tutorial uses

UserName1

and

12345

as the

username and password.

3

Log into www.dyndns.org using your account.

4

Add a new DDNS host name. This tutorial uses the following settings as an

example.

• Hostname:

zyxelrouter.dyndns.org

•

Service Type:

Host with IP address

•

IP Address: Enter the WAN IP address that your ZyXEL Device is currently using.

You can find the IP address on the ZyXEL Device’s web configurator

Status

page.

Then you will need to configure the same account and host name on the ZyXEL

Device later.
