    No Internet Connection When VPN Is Connected

    This particular issue has been going on for almost a month now. My companies IT department is still trying to figure out the root cause. Below is a list of isolation / troubleshooting i've done.

    Issue: Once connected to the work VPN (successfully) the internet connection on the Windows 10 machine disconnects and does not allow any network traffic.

    OS: Windows 10 Home - Version: 1909 (OS Build 18363.476)

    Computer: Razor Blade 2019

    - Latest drivers installed

    - Latest Windows updates installed

    - System Wide issue

    Troubleshooting / Isolation

    • Cellular Data: Verified the Windows machine can connect to a hotspot and successfully browse the internet. (No VPN involved)

    • Cellular Data + Work VPN: Verified the Windows machine can connect to the hotspot & successfully connect to work VPN and successfully browse the internet.

    • Home WiFi: Verified Windows machine can connect to the home wifi network and successfully browse the internet (No VPN involved)

    • Home WiFi + Work VPN: Verified Windows machine can connect to home WiFi. It can successfully connect to work VPN. However once the work VPN is connected, the home WiFi network indicates (No Internet Access)

    • Ping Test + Work VPN: Verified I can successfully ping (work) websites and even the work VPN URL successfully without any packet loss. However once I go to ping (non-work) related addresses like google.com, apple.com etc. there is packet loss.

    At this point I decided to test my work VPN on my iPhone & Apple Mac.

    • iPhone: Home WiFi + Work VPN: Verified the iPhone successfully connects to home WiFi network and the work VPN and can successfully browse the internet.

    • Mac: Home WiFi + Work VPN: Verified the Mac successfully connects to home WiFi network and the work VPN and can successfully browse the internet.

    Isolated: Only the Windows machine seems to be affected. I even verified this issue occurs on multiple Windows user accounts on the Windows 10 machine.

    - Windows 10 is fully updated to the latest November Windows 10 update and issue persists

    - Deleted and Added the VPN configuration several times and issue persisted.

    Third Party VPN Client Test: Tested with Nord VPN and the Windows machine successfully connected to the home WiFi network & the Nord VPN connection successfully connected to a random server and successfully browsed the internet.

    - Disabled IPV6 on VPN & WiFi network configuration (Per IT Support guidance) and issue persisted

    *Currently updating to Windows 10 Insider Preview 19033.1 (vb_release) to see if this might fix anything pertaining to Windows 10 VPN.

    Thanks for any additional guidance / suggestions / help that the community offers.
