SmartRG SR400ac - How to Set Up DNS Filters

IMPORTANT NOTE:  Please ensure that any Parental Controls from SmartRG are turned OFF after logging into your router administrative settings.  If they have Parental Controls, they may cause conflicts with FreeFiltering.


You'll need to set up your SmartRG router to use our "Standard DNS Servers" located on your "Settings" page:

  1. Go to from a browser that is connected to your Wi-Fi network.  If this does not bring you to a log-in page, reference your user manual or the label on your router for how to log in to the router administrative settings.

  2. Enter the username and password.
    The default username should be admin. The default password should also be admin.  (Unless you've customized them at some point in the past.)  If admin and password don't work, check your router box for a label that might list a different default username and password or ask a family member if they've set up a unique password already.  After successfully logging in, we recommend changing the password required for logging into your router settings and storing it securely.  This will prevent someone from logging into your router and making unauthorized changes.

  3. Click "Network"

  4. Under "Network", click "Routing", then "DNS".  Then click the "plus symbol" under "IPv4/UPv6 Address" / "Actions".

  5. Enter both addresses listed under "Standard DNS Servers" from your FreeFiltering "Settings" page.  It does not matter what order you enter them.  NOTE:  The addresses listed on your "Settings" page may be different than those below!

  6. Next, click "DHCP Server" under "LAN Network" in the menu.  Under the section entitled "DHCPv6 Server" toggle the "Enabled" button OFF.

  7. Click "Ethernet WAN" under "Network" in the menu.  Scroll down the page.  Toggle the "Allow DNS Server List Override" button OFF for both the "IPV4 CONFIGURATION" and "IPV6 CONFIGURATION" sections.

  8. Next, click "Status" under "Network".  You should see only the FreeFiltering "Standard DNS Servers" that you previously entered.  NOTE:  Your "Standard DNS Servers" may be different than the ones pictured below.

  9. After the new DNS settings have been applied, try visiting several of the abortion provider websites listed here to ensure your filters are working.
