Specify Your Network Settings

Most ISPs (Internet service providers) assign a dynamic IP address to the router and 
you can use this IP address to access your router remotely. However, the IP address can 
change any time and you don’t know when it changes. In this case, you might need 
the DDNS (Dynamic Domain Name Server) feature on the router to allow you and your 
friends to access your router and local servers (FTP, HTTP, etc.) using domain name, in 
no need of checking and remembering the IP address. 

Note: DDNS does not work if the ISP assigns a private WAN IP address (such as 192.168.1.x) to the modem router. 

To set up DDNS, please follow the instructions below:
1   Visit 

, and log in with the password you set for the modem 

router.

2   Go to 

Advanced 

> 

Network

>

 Dynamic DNS.

3   Select the 

DDNS service provider

 (Dyndns or NO-IP). If you don’t have a DDNS 

account, select a service provider and click 

Go to register

.

4   Enter the username, password and domain name of the account (such as lisa.ddns.

net).

5   Click 

Login

 and 

Save

.

Tips: If you want to use a new DDNS account, please Logout first, then login with the new account.

Divide my devices connected to the modem router into different 
groups and disallow devices’ cross-group communication.

For example

, in my house, devices connected to LAN1 and LAN3 

are for work, while others for entertainment. I want to isolate 
working devices from others while keep all devices’ access to 
the Internet.
