OpenDNS

OpenDNS is a free service offered to act as parental controls. By replacing Nex-Tech's auto-obtained DNS servers with static DNS servers that are provided by OpenDNS, computers will be blocked from pornography, proxy servers, phishing sites and some malware. OpenDNS may be used on a single computer or within a router so that every computer on the network will have the filters enabled.









Setting Up OpenDNS On Your Router

Choose your brand of router:





Setting Up OpenDNS On A Comtrend Router

  1. Visit the router's IP address
    Open up your web browser (Internet Explorer, Firefox, Chrome, etc.) and clear out the address bar at the top. Now type in 192.168.1.1 and press Enter




  2. Enter the Network password
    Next you should have a popup asking for a User Name and Password. The User Name is user and the Password is user. Then press OK.
    NOTE: If this User Name and Password doesn't work, you may also try the following:
    User Name: root   Password: central
    User Name: root   Password: 12345
    User Name: support   Password: support




  3. Enter the Advanced Setup
    Once logged in to the Comtrend router, click on Advanced Setup on the left side of the screen. Then click on DNS.




  4. Towards the middle of the page, put a check mark next to Use the following Static DNS IP address and type in the following DNS server addresses:
    Primary DNS server: 208.67.222.123
    Secondary DNS server: 208.67.220.123

    Once the addresses are typed in, click Apply/Save at the bottom of the page.




  5. You may need to reboot the Comtrend by unplugging the power cable and plugging it back in for the changes to take full affect. Once this is complete, you should be protected by OpenDNS.

    Next you should have a popup asking for a User Name and Password. Skip the username and the default password should be admin, unless you have manually changed the password, and then press OK.




  3. Type in OpenDNS addresses in Static DNS 1 and Static DNS 2 fields
    On the first page that loads, there should be a spot that has options for different static DNS (you may need to scroll down just a little bit). By default, they will all have 0's in the boxes. Change the following static DNS boxes to the following numbers:
    Static DNS 1: 208.67.222.123
    Static DNS 2: 208.67.220.123




  4. Click Save Settings button
    After you have typed in the the numbers for both Static DNS 1 and 2, scroll all the way to the bottom and press Save Settings.
