Latest Mbam on 1909 Breaking Private Internet Access Split-Tunneling

Recommended Posts

On 1903, everything was functional.  Upon updating to Windows 10 1909, PIA can no longer split tunnel (having certain programs excluded from the VPN).  PIA and all associated files have been excluded from detection, as well as turning Potentially Unwanted Items to warn instead of automatic , yet, Web Protection is still interfering.  Mind you, not a single time have I received a notification of something being blocked or prevented from acting.

Upon disabling Web Protection, PIA Split-Tunneling is once again functional.  PIA support has directed me here, since it was determined to be an issue with Mbam.  

 

The only change between it functioning correctly, and now not functioning, was updating from Windows 10 Pro 1903, to W10 Pro 1909.  Over on the PIA reddit, someone else has stated that the latest Mbam itself has broken Split-Tunneling, but they are on Windows 7.  Mbam could of updated in the background without me realizing, but either way, the issue is Web Protection interfering somehow.  

 

TLDR; Either Mbams latest version, or Mbams functionality on Windows 1909, has broken the functionality of PIAs split-tunneling via Web Protection.

To exclude an item from Web Protection you must exclude it by selecting the Allow an application to connect to the Internet option as described in the section of the same name in this support article.  If Web Protection is blocking it, you should be able to exclude it that way and Malwarebytes should stop blocking it.

I hope this helps and if there is anything else we might assist you with please let us know.

Thanks

Wouldn't of made an account and this post if excluding it was functioning correctly.  The whole point of this point is literally that it's NOT excluding it, even with being allowed. 

 

On top of that, Mbam doesn't even say it's detected or prevented any modifications or tampering.

You stated in your post that you excluded from detection and as potentially unwanted; the exclusions for Web Protection are completely separate and must be created individually/separate from exclusions from other modules/components.  Your initial post never mentioned that you created exclusions from Web Protection using the Allow an application to connect to the internet which is why I instructed you to do so; that is the only way to exclude an application from Web Protection.  If you already did so, good, however if you did then it can't be Web Protection blocking it unless it is some sort of driver conflict as Malwarebytes allows all communications to/from any process excluded that way.

I stated "PIA and all associated files have been excluded from detection, as well as turning Potentially Unwanted Items to warn instead of automatic".  In addition to the folder exclusion, I did manually exclude all executables that PIA support told me to, via "Allow an application to connect to the internet". 

 

As I said before, its not excluding it from web protection.  Disabling web protection does fix it, but its non ideal to go with that mbam feature disabled.

Nope.  Only Mbam Premium 4.0.4.49,

Update Package version 1.0.17784

 Component package version 1.0.793

Mbam states its up to date when manually checking.

Yes, it must be conflicting then unfortunately.  Web Protection in Malwarebytes uses WFP; the same API's and framework as the built in Windows Firewall.  It sounds like something about how Web Protection is filtering is interfering with the Split-Tunneling feature.

If you would, please do the following so that we may gather data about the issue for the Developers and for further troubleshooting purposes:

  1. Download and run the Malwarebytes Support Tool
  2. Accept the EULA and click Advanced tab on the left (not Start Repair)
  3. Click the Gather Logs button, and once it completes, attach the zip file it creates on your desktop to your next reply

Thanks

Been trying to untangle what I thought was a network configuration rabbit hole for the last 2 days... and it was MB all along? 😡
Well, at least I know what the problem is now... 😪

I'm having the exact same problem. When web protection is on, it messes with PIA's ability to split tunnel an application.
When i tern web protection off, all is fine. But when i tern it back on. the split tunnel fails and the application sends all its traffic through the vpn.

I have added a bunch of PIA's executables as exclusions, and allowing them to connect to the internet, but nothing worked.

I also did not get any pop ups from MB that indicated that it blocked any connections or applications.

Version: 4.0.4.49
Update pack: 1.0.18922
Component Pack 1.0.810

The issue has been resolved as far as I can tell from the update I received today that prompted me to restart Mbam.

Web Protection and all other Mbam features are active, and PIA VPN split tunneling is once again fully functional.  

Though I have no idea what the update was.

Mbam V 4.0.4.49,

Update Package V 1.0.19012, 

Component Package V 1.0.823

 

Glad to see it fixed within a month.  Though I do not know if it was intentional, or a happy byproduct of part of you guys updating something else.

Excellent, I'm glad to hear it :) 

Please do let us know if the issue returns or if you experience any other problems with the software.

I am not so lucky... However, it does look like the behaviour has changed... Before. The moment web protection was turned on, the split tunnel failed and traffic was going through the VPN. However, now, if you launch the app and it is split tunnelled by PIA, web protection does not immediately clock onto it when turned on. it only interferes if the program is closed and then relaunched while web protection is on.

I have also noticed that both PIA and Malware bites use Qt for cross platform app development. May this be why PIA users are being affected? If both are using the same network API for network manipulation, then that may be causing the conflict.

@Reaper511 Can you confirm that your split tunnel is still working after doing the following?
Tern web protection on, then completely close and reopen the application you have configured to bypass the PIA VPN. Then check to see if your application is connecting through your IP or through the PIA network.

@exile360 I'm setting up a VM today to run Windows 10, Malware bites and PIA only so the logs will be as clean as possible for your engineers to have a gander. :)

@LiquidTension some logs and details on replication via a clean VM provided above for further diagnostics purposes.

Thank you again to everyone who has helped to track down this issue.  Hopefully they will have a fix available soon.

Initially it was functional as normal.  But I have found the issue again and have narrowed it down.

 

My standard use is to have only one singular application to run through the VPN.  So previously I would select multiple applications to bypass the VPN and the one to be Forced through the VPN.  By default, any non specified apps would run through the VPN. Recently I updated to the PIA Beta, which added the additional option to set "All Other Apps" to either bypass the VPN, or to use the VPN.  During my initial post I did not have All Other Apps set to bypass.  Upon setting All Other Apps to bypass (besides the specific ones i have set to run through the VPN), it becomes functional again.

 

The issue still persists if you have have AOApps set to run through VPN.  From that, it appears that some specific app or service being ran through the VPN is causing Mbam to interfere.  But while not being ran through the VPN, Mbam doesn't care, yet my specified apps that are set to run through the VPN, are appropriately running through it.

That's not the case in my VM setup.
1. Start PIA beta and set Firefox to VPN only, with everything else set to bypass.
2. Make sure web protection is off.
3. Launch Firefox and Edge and google my ip.
4. Edge shows my ip - Firefox shows VPN ip (OK)
5. Close both browsers.
6. Tern web protection on.
7. Repeat step 3.
8. Edge and Firefox show my ip. (FAIL)
9. Tern off VPN.
10. Firefox can not connect to the internet. (OK) This is intended behavior as it is set to VPN only.
11. Tern on VPN.
12. Edge and Firefox show my ip. (FAIL)

So... The VPN's split tunnel is correctly blocking traffic when turned off (as it should) with web protection on. Yet fails to split tunnel the traffic through the VPN when the connection is established.

More info i have found.

Split tunnal data route. no web protection
Local address Bypass: 192.168.0.(MY PC) (OK)
Local address VPN: 10.2.11.6 (OK)

When the VPN split tunnals data. web protection on.
Local address Bypass: 10.2.11.6 (FAIL)
Local address VPN: 10.2.11.6 (OK)
