This maps e-mail traffic coming from port 25 to the highest priority, which you have created in the

previous screen (see the

address to the

E-mail

queue (see the

Source

fields).

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 Device Using DDNS

If you connect your 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 Device’s WAN IP address changes dynamically.

Dynamic DNS (DDNS) allows you to access the Device using a domain name.

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

This tutorial covers:

•

Registering a DDNS Account on www.dyndns.org

•

Configuring DDNS on Your Device

•

Testing the DDNS Setting

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

4.7.1

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 Device is currently using. You can find the IP

address on the Device’s Web Configurator

Status

page.

Then you will need to configure the same account and host name on the Device later.

www.DynDNS.com

as the service provider.

•

Type

zyxelrouter.dyndns.org

in the

Host Name

field.

•

Enter the user name (

UserName1

) and password (

12345

).

Click

Apply

.

4.7.3

Testing the DDNS Setting

Now you should be able to access the Device from the Internet. To test this:

1

Open a web browser on the computer (using the IP address

a.b.c.d

) that is connected to the

Internet.

2

Type

and press [Enter].

3

The Device’s login page should appear. You can then log into the Device and manage it.
