Dynamic DNS

System > DDNS

When using a dynamic IP/DHCP WAN type from your ISP where your public IP or

Internet IP address always changes, dynamic DNS provides a method of accessing your

router or network remotely over the Internet for devices such as IP cameras, storage, or

computers hosted on the local LAN side of your router. Dynamic DNS services do thi by

assigning a custom hostname or DNS name for you to reference. Your router will send

updates to the dynamic DNS service provider if the WAN or Internet IP address(es)

change providing the emulation of a virtual fixed IP address that you can always

reference to access your router over the Internet.

Note: First, you will need to sign up for one of the DDNS service providers listed in the

Server Address drop-down list.

Note: In multi-WAN mode, you can configure a DDNS service for each WAN interface.

1. Sign up for one of the DDNS available service providers list under Server Address.

(e.g. no-ip.com, dyndns.org etc.)

2. Log into your router management page (see “Access your router management page”

on page 7).

3. Click on System and click on DDNS.

4. Next to one of the entries, click Edit. Review the DDNS settings below.

• Active – Check the enabled option to enable the dynamic DNS entry.

• Provider: Click the drop-down list Select your DDNS service.

• WAN: Click the drop-down list and select the WAN interface for the DDNS

service.

Note: To ensure resolvability, it is recommended to assign each DDNS entry to a

specific WAN interface.

• Host Name: Enter the custom hostname or DNS name you created with DDNS

account. (e.g. trendnet.ddns.net)

• Account: The user name needed to login to your Dynamic DNS service account.

• Password: This is the password to login to your Dynamic DNS service account.

• Interval – This specified the time interval between each DDNS update sent the DDNS

service provided. Please refer to your DDNS service provider requirements.

5. Click Save at the bottom. Then click Reboot at the top right to commit the changes.
