Bitdefender firewall wont allow WSL traffic

in Firewall

Hi there,

I've just installed Bitdefender total security 2020 and I can't seem to get any traffic through WSL2 (windows subsystem for linux). Does anyone know how to allow this or what settings? I've tried a few things but the only thing that works is reverting back to using the Windows Firewall.

Many thanks,

Xephys

    Hi there,

    Are there any updates on this?

    I am experiencing the same issues.

  • tryugfbhtryugfbh ✭

    I have the same issue.

    Disabling BitDefender firewall fixes it.

    Guys, this is ridiculous... We pay for a product that doesn't work as intended and there's not even a response for 2 months regarding this issue. Could you at least tell us whether you're aware of it, you're working on it or you can't do anything about it, since it may be WSL2/Windows related or whatever... Just give us feedback.

    Hi Member

    Kindly drop an email to bitdefender support at [email protected] regarding your query. These types of issue can only be handled by bitdefender support since they can connect internally with the development team to provide you with a feedback.

    Support on forum is limited to basic troubleshooting of the bitdefender products.

    I just renewed my license, and moved my dev env to WSL, if I´d known about this I wouldn't have renewed it

    I set vEthernet adapter as public network, manually added and approve any traffic for svchost.exe (for main adapter, for me it's ethernet) and everything is ok now. Can anybody confirm?

  • MateoFMateoF ✭

    After allowing "C:\Windows\System32\svchost.exe", it works for me.

    Windows 10 Pro using Ubuntu installed under WSL2

    Bitdefender Total Security: Build 25.0.14.58 - paid version

    Thank you to everyone above.

    In the process of setting up a Windows dev environment using WSL2, I was getting "error: curl: (6) Could not resolve host" even when I tried "curl example.com" from Ubuntu installed under WSL2. No notifications from Bitdefender but just happened a few posts that made me realize Bitdefender is the culprit.

    This post: https://github.com/microsoft/WSL/issues/3761 - suggested running the following command under Ubuntu so I could clearly see what antivirus software is running on my system:

    $ powershell.exe "Get-CimInstance -Namespace root/SecurityCenter2 -ClassName AntivirusProduct" | grep displayName

    And helped make it clear that I need to opt for one of the follow solutions in my configuration of BitDefender (BD):

    "If you pause BD protection, HTTPS still fails. But you do not need to fully uninstall it. You can simply exit it before running some HTTPS requests in WSL and start it again after.You can also modify some Network settings. There are 3 solutions:"

    * Disable monitoring of HTTPS/443 port
 
* Disable encrypted connections scanning
 
* Add the domain names you usually call, like those called by apt update

    I tried adding a rule specifically for Ubuntu but because it is installed under WSL2, the path is not seen as valid by BitDefender.

    What I opted for, which is not optimal, is to add Firewall Rule as follows:

    Program path: C:\Windows\System32\svchost.exe

    Permission: Allow

    Network Type: Home/Office

    Protocol: 6. TCP

    Direction: Both

    Under Advanced Settings >> Ports (for local and remote): 443

    And then rebooted my machine.

    I figure, until BitDefender fixes the issue that will allow me to add Ubuntu specifically or I change protection programs, I'll just enable/disable this rule as needed.

    I would love to hear another way around this if possible. I'll try sending an email to BitDefender...
