D-Link routers employ various DNS filtering features for security. These however conflict with UnoDNS and need to be disabled. 

Depending on the model, please disable the following features if they are available on your model.

  • Disable "Enable Advance DNS services"
  • Disable "Enable DNS relay"
  • Disable "Auto DNS"
  • Disable "Enable anti-spoof checking" from Advanced -> Firewall Settings
  • Some routers override your DNS settings if logged in with a MyDlink account.Restore the Dlink to factory defaults and test the connection without logging into a MyDlink account. 

Once disabled, please reboot your router and your devices and try again.
