Access Your Home Computer from the Internet Using
DDNS
It is inconvenient for you to access your home computer from the Internet if your VDSL Router uses
a dynamic WAN IP address since it changes dynamically. Dynamic DNS (DDNS) allows you to
access your home computer using a domain name.
Note: Enable remote desktop server service on your home computer. The remote desktop
server feature covered here is included in Windows Professional, Business, and
Ultimate versions.
Note: If firewall is enabled, you may also need to configure a firewall rule for the relevant
ports. See
Section 2.9.2 on page 35
.
To use this feature, apply for DDNS service at www.dyndns.org or TZO. This tutorial covers:
•
Registering a DDNS Account on www.dyndns.org
•
Configuring DDNS on Your VDSL Router
•
Configuring Port Forwarding on your VDSL Router
•
Testing the DDNS Setting
Note: If you have a private WAN IP address, then you cannot use DDNS.

•
IP Address: Enter the WAN IP address that your VDSL Router is currently using. You can find the
IP address on the VDSL Router’s Web Configurator
Status
page.
Then you will need to configure the same account and host name on the VDSL Router later.
