A Dynamic Domain Name System (DDNS) allows Internet access to the server through the use of  a domain name rather than an IP address. DDNS also maintains IP address information even when the client receives a dynamic IP assignment which is subject to constant change by the ISP. With this configuration, the server is always available regardless of the IP address. This service is only usable after you establish an account with a DDNS service provider. The DNS server must be entered on Administration > Network > TCP/IP. This comes from the ISP as well.

The objective of this document is to show you how to configure the DDNS Settings on the NSS300 Smart Storage series.

Applicable Devices

• NSS300 Series Smart Storage

Software Version

• v1.5.0

Configure DDNS Settings

Step 1. Log in to the web configuration utility and choose Administration > Network > DDNS. The DDNS page opens:



Step 2. Check the Enable Dynamic DNS Service check box to enable the DDNS service.

Step 3. From the Select DDNS Server drop-down list, choose a DDNS server. The available servers are as follows: www.tzo.com, www.dyndns.com, update.ods.org, members.dhs.org, www.dyns.cx, www.3322.org, and www.no-ip.com.

Step 4. In the Username field, enter the username registered with the DDNS provider.

Step 5. In the Password field, enter the password registered with the DDNS provider.

Step 6. In the Host Name field, enter the host name registered with the DDNS provider.

Step 7. (Optional) Check the External IP Address Automatically check box to have the device check for any changes in IP address. Choose the desired time interval in the drop-down list. The time intervals available are as follows: 10 minutes, 15 minutes, 20 minutes, 30 minutes, and 1 hour.

Step 8. (Optional) Check the Update DDNS using the alternate port 21333 (bypass local web proxy) check box to have the DDNS use port 21333.

Note: If a recent DDNS update has been done, the results will display in the following fields.

• Connection IP Last Checked — Indicates the WAN IP address last checked.

• Next Check for Connection IP — Shows the time schedule that WAN IP address will checked.

• Last DDNS Update Time — Indicates the last time the DDNS was updated.
