Step One – Open the main system configuration window

In the main windows of the console for the EdgeMAX Router, click on the System button towards the bottom left of the window. This will bring up the main system configuration screen.

Step Two – Under “Name Server” configure the “System Name Server” values

Add the first OpenDNS IP address in the text field (208.67.222.222).  Click the Add New button to add a second text field, then enter the second OpenDNS IP address into that field (208.67.220.220).  Scroll down to the bottom of the System settings and click the Save button.

Step Three – Login to the command line interface

In the upper right section of the admin interface, click on the CLI button to open a window to the command line interface.  When the window opens, login using the same username and password you use for the web interface.

Step Four – Update the DNS Forwarding

After logging into the CLI, you need to enter the following commands, remember to hit enter after each command line entry:

configure
set service dns forwarding system
commit
save
exit
exit

What this does is to alter the functionality of the built-in DNS forwarding service to use the system name server values instead of the values from your ISP source.

You can run the following command to see what DNS setting are now active.

show dns forwarding nameservers

After you have completed the above steps, then you can easily control the content filtering on your network using the OpenDNS tools.
