Firewall issue, after updating Windows 10

edited February 2 in Install & Updates

Hi. After updating WINDOWS 10 PRO 22H2, the firewall from Bitdefender Total Security does not allow any application to work, as well as to access the internet. 

In order for the applications to work and have access to the internet, I either have to close the firewall from bitdefender or add manual a rule for the applications to be free.

The funny thing is that bitdefender doesn't even let bitdefender VPN access the internet.

    My specs:

    OS Windows 10 Pro 22H2 x64 With Latest Windows Updates Installed

    Installed On 18.01.2023

    OS Build 19045.3996

    Experience Windows Feature Experience Pack 1000.19053.1000.0

    BD Total Security

    So far, no problems with the firewall, all applications on my device work without any problems and with full access to the internet.

    Do the steps below.

    -- STEP 1 --

    Repair Bitdefender, by following these steps:

    -- STEP 2 --

    If the instructions from Step 1 didn't help, uninstall the Bitdefender program using the Uninstall Tool:


    It will completely remove the program.

    Next, reinstall Bitdefender from your Bitdefender Central account and see if the issue has been solved, as reinstalling the program usually solves the issues.

    -- STEP 3 --

    If the instructions from Step 2 didn't help, follow the instructions in this step.

    First, take screenshot(s) of the issue

    and create a log file on your Windows device using Bitdefender Support Tool, by following these steps:

    Next, contact Bitdefender Consumer Support by e-mail:

    with short description of the issue.

    After that, you will get an automated reply by the Bitdefender Customer Care Team, with your ticket number.

    Now, in reply to that automated reply, you can send the screenshot(s) you already took and the log file you already created in the first step.

    Since you are all done, just wait for the support engineers to investigate your issue and find a solution to fix the issue.

    Remember that the screenshot(s) and the log file will help a lot to the support engineers for better and faster investigation on your issue and finding a solution.

    NOTE: If the log file is larger than 25MB, you can upload the log file here:

    After the upload is done, you will get a notification with the file's URL and then you can share the file's URL with the Bitdefender Consumer Support.

    Hello @aapostolos,

    In addition to @Gjoksi's insightful information above, try the following:

    1. Go to Network Adapters tab and set the network type to Home/Office using the drop-down menu near its name

    2. Then, from the same Firewall Tab, click on Settings from the top-right , then, for the network you're currently connected to, uncheck the stealth mode button to disable it.

    If this doesn't help, go to Firewall -> choose Rules tab, then reset Rules. Restart Windows and check if the device can connect to the Internet.

    Regarding the VPN, if you can connect it after disabling the Firewall, try this:

    1. Go to Network Adapters tab and set the network type to Home/Office using the drop-down menu near its name(do this for all present adapters).

    2. Then, from the same Firewall Tab, click on Settings from the top-right, then, for all networks shown, uncheck the stealth mode button to disable it.

    3. In the same tab, set the default behavior to Allow for all adapters, apart from the one you're currently connected to. If the issue persists, go to Firewall Settings tab and deactivate the Block port scans in the network option.

    In the event the above procedure fixes the issue, go to Firewall settings again and click on the Rules tab. Locate your VPN process and set the permission status to Allow by clicking on the 3 little dots near the process name -> Edit Rule -> set Permission slider to enabled(blue). If no rule for your VPN is created, create a new rule and make sure you set the permission status to Allow.

    If nothing helps, contact the Bitdefender Support teams and provide them with the following information:

    1. A connectivity log:

    2. Support Tool log:

    3. If the issue occurs on Wi-Fi and LAN

    I hope the information is helpful.
