Cannot enable Bitdefender Total Security Firewall

Hi, I'm on Windows 11. On my Protection dashboard in Total Security, my Firewall is disabled and when I try to reenable it, the toggle goes back to grey again. My Base Filtering Engine is on Automatic startup and is running, but I simply cannot get the firewall to toggle on. Any suggestions?

  • Hello @Melphis,

    Check if this article helps. It covers both scenarios, BFE on or off:

    If this doesn't help, check for other security solutions that might be installed on the device and uninstall them.

    If this is not the case, follow the guideline from this Microsoft article, then restart the computer and try again to activate Bitdefender Firewall:

    It regards Windows Firewall but the fix also work for Bitdefender Firewall.

    If the Firewall still doesn't stay enabled, apply these steps:

    1. Go to Start -> in the Search bar type regedit and hit the Enter key.

    2. In the Registry Editor window browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip

    3. Click on Tcpip then look in the right side and search for the Start key. Double click on it and change the Value data to 0.

    4. Restart Windows and try again to activate the Firewall.

    In the event the issue pesists after trying the above solutions, you may need to update the network adapter driver.

    You can install it from the manufacturer's official website or update it from Device Manager: go to Start > in the Search bar type Device Manager and hit Enter > wait for the list to be populated then expand the Newtork adapters entry > right-click on each entry and select Update Driver Software > choose Search automatically for updated driver software. Once the process completes reboot the computer. Then reinstall Bitdefender from Control Panel.

    These instructions should cover all scenarios, but if somehow the Firewall still refuses to stay enabled, you'll have to contact the Support teams for a more in-depth investigation.

    I hope the information is helpful.
