VMG5313-B10A/-B30A Series User’s Guide

This maps e-mail traffic coming from port 25 to the highest priority, which you have created in the 
previous screen (see the IP Protocol field). This also maps your computer’s IP address and MAC 
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.

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:

•

•

•

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

Open a browser and type http://www.dyndns.org.

Apply for a user account. This tutorial uses UserName1 and 12345 as the username and 
password.

Log into www.dyndns.org using your account.

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.
