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.

Configuring the MAC Address Filter

Thomas noticed that his daughter Josephine spends too much time surfing the web and

downloading media files. He decided to prevent Josephine from accessing the Internet so that she

can concentrate on preparing for her final exams.

Josephine’s computer connects wirelessly to the Internet through the Device. Thomas decides to

use the

Security > MAC Filter

screen to grant wireless network access to his computer but not to

Josephine’s computer.
