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.

 

After connecting to VPN the internet breaks down

Hello David,

thank you so much for your detailed manual. Unfortunatelly, even though I followed all your steps, nothing changed.

When I connect to VPN, the status of the connected wifi router changes to "no internet".

I also reseted all computer in order to clean it. So the system should be clean and up to date.

Is there any suggestion, what I could try in order to have VPN going?

Thank you!

Is it possible to share internet connection via remote desktop?

RDP is not capable of Internet sharing, so you can't share Internet using RDP with standard applications. There are many way to share Internet from a Windows box to another one. I suggest you to use VPN. You should do following steps:

1. Run VPN Server on your server with unlimited internet access
   
2. Connect to VPN server from your limited computer
