3.6 Using DDNS to access the N4100
If you connect your N4100 to the Internet and it uses a dynamic WAN IP address,
it is inconvenient for you to manage the device from the Internet. The N4100’s
WAN IP address changes dynamically. Dynamic DNS (DDNS) allows you to access
the N4100 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 N4100
• Testing the DDNS Setting
Note: If you have a private WAN IP address, then you cannot use DDNS.
3.6.1 Registering a DDNS Account on www.dyndns.org
1 Open a browser and type http://www.dyndns.org.
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 N4100 is currently using. You
can find the IP address on the N4100’s Web Configurator Status page.
Then you will need to configure the same account and host name on the N4100
later.
