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
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
•
•
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.
