FRITZ!Box reports "Access to the fixed IP address [...] was prevented by the website filter"

A device or application (for example Amazon Fire TV or Netflix) cannot access the internet. The following message is displayed in the event log of the FRITZ!Box:

"Access to the fixed IP address [...] was prevented by the website filter."

Cause

  • The filter for web pages (blacklist, whitelist) is enabled in the parental controls for the device. This prevents the device from directly accessing IP addresses on the internet.

Perform the step that is appropriate for you.

Note:The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS for your FRITZ!Box.

1 Disabling parental controls for the device

If it is not necessary to configure parental controls for the device, assign the device to the "Unrestricted" access profile to disable them:

  1. Click "Internet" in the FRITZ!Box user interface.
  2. Click "Filters" in the "Internet" menu.
  3. Select the access profile "Unrestricted" for the respective device from the drop-down list.
  4. Click "Apply" to save the settings.

2 Disabling filters for websites

If you want to continue to limit the internet access time but do not need to restrict the websites that can be accessed, disable the web page filter for the access profile that the device is assigned to:

Note:The "standard" profile is valid for all devices in the home network that have not been assigned to a specific access profile. The profile "Guest" applies to all devices in the guest network.

  1. Click "Internet" in the FRITZ!Box user interface.
  2. Click "Filters" in the "Internet" menu.
  3. Click the button (Edit) for the access profile you would like to configure.
  4. Disable the option "Filter web sites".
  5. Click "OK" to save the access profile.
