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

the bandwidth allotted to e-mail traffic compared to other network traffic.
4.9 Access the SBG3500-N Series Using DDNS
If you connect your SBG3500-N Series to the Internet and it uses a dynamic WAN IP address, it is
inconvenient for you to manage the device from the Internet. The SBG3500-N Series’s WAN IP
address changes dynamically. Dynamic DNS (DDNS) allows you to access the SBG3500-N Series
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 SBG3500-N Series
• Testing the DDNS Setting
Note: If you have a private WAN IP address, then you cannot use DDNS.
4.9.1 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.

•Hostname: zyxelrouter.dyndns.org
•Service Type: Host with IP address

find the IP address on the SBG3500-N Series’s Web Configurator Status page.
