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

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