previous screen (see the

to the E-mail queue (see the Source fields).
4.7 Access the EMG Using DDNS
If you connect your EMG to the Internet and it uses a dynamic WAN IP address, it is inconvenient for you
to manage the device from the Internet. The EMG’s WAN IP address changes dynamically. Dynamic
DNS (DDNS) allows you to access the EMG 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 EMG
• 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 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 EMG is currently using. You can find the IP address on
the EMG’s Web Configurator Status page.
Then you will need to configure the same account and host name on the EMG later.
