Windows 10 shows No internet after VPN connection is established.

The internet is connected to the system but after the VPN is connected the internet connection is dropped automatically and the system shows "No Internet". I have tried to remove the VPN and add it again but it did not help.

@Mintu Kumar

Here are some quick work around you can try:

Make sure the additional routes are only advertising the required additional routes or is empty

Redownload the VPN Configuration file from the VPN Gateway and then re-import the configuration file into the VPN Client App

If the above does not help,

Let's try and confirm the issue is whether routing related or DNS related.

After connection to the P2S, Open Powershell as Admin and run

nslookup www.google.com

nslookup www.google.com 8.8.8.8

Test-NetConnection -ComputerName dns.google -Port 443

Test-NetConnection -ComputerName 8.8.8.8 -Port 443

And share the output please.

Cheers,

Hi Kapil,
The problem is not resolved yet.
It is interesting that the internet is working in the Edge browser, but I cannot ssh to other machines using the ubuntu terminal.
Here is the output of the PowerShell:

@Mintu Kumar

Then it means Internet is working as expected.

Can you please elaborate on what do you mean by "but I cannot ssh to other machines using the ubuntu terminal." ?

Are these Linux machines hosted on the Internet?

"Using the ubuntu terminal" - I believe you were using Windows machine, please correct me if I am wrong.

Does SSH using Putty work?

I am not clear on how and why Linux comes into picture here.

I would appreciate if you could elaborate about your environment, so that we can troubleshoot the issue further.

Cheers,

Kapil

Hi @KapilAnanth-MSFT
Okay, so I have installed Ubuntu from the Microsoft store. I usually used Ubuntu to run some of the software and ssh to other Linux machines. In principle, we can use Powershell for ssh, which works well.

I have reinstalled and updated the Avanti software for ssh, and it works fine now, even with Ubuntu. But the network connection still shows "No Internet" even if the Internet is working fine, as shown below Image.
Thanks Mintu

@Mintu Kumar

I doubt this is related to Azure VPN Client.

This seems to be related to your OS (an isolated incident) and I believe we would require a specialized 1:1 session, where a support engineer can have a screen share session to pinpoint the issue. If you have a support plan you may file a support ticket, else please do let us know, we will try and help you get a one-time free technical support.

Meanwhile, I shall summarize our discussion and post it as an answer, I would highly appreciate if you could Accept the answer and close this thread as it may benefit other community members.

Do let me know should you have any further queries.

Hello @Mintu Kumar !

Welcome to Microsoft QnA!

You have a Routing Problem

If you have control over the VPN you can go to

VPN - Scroll Down - Change adapter options and find the Connection

Right Click - Properties -Networking - TCP/IP v4 and Advanced

In Ip Settings UNCHECK Use Default Gateway , in this way routing is going through your PC for all , except the VPN Networks

I hope this helps!

Hi @Konstantinos Passadis ,
My setting is not exactly the same as yours. To me, it seems like this, where I do not find the setting you have shown.

Hello

You have to find the VPN connection!

If it not there as an adapter , then is is a Vendor specific like Cisco etc

Can you describe if you see it listed along with the WIFI connection ?

Although not 100% relevant for my case, your comment inspired me to check the DNS settings. I then did a manual override to have my DNS server set to my VPN server's internal IP address, and all is well again.

@Mintu Kumar

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I understand that your machine says "No Internet available" after connecting to Azure P2S VPN.

I suggested to check if this is a DNS issue or routing issue.

Interestingly, Internet seems to work from CMD and browser, only that the Windows Notification says that there is no Internet.

In this case, I suspect this an OS related issue (an isolated incident) and I believe we would require a specialized 1:1 session, where a support engineer can have a screen share session to pinpoint the issue.

Are you able to repo this issue in any other local servers?

Kindly let us know if this helps or you need further assistance on this issue.

Thanks,

Kapil

Aren't you using Azure VPN Gateway?

I assumed you are using Azure VPN Gateway since you have tagged it.

Refer : P2S VPN Gateway Azure

Hello friend
I had the same problem and none of the solutions above my comment worked for me.
I fixed it myself , This is what I did : Go to Control Panel - Net Con - Wi-Fi - Internet Protocol Version 4 - Advanced - WINS - Change Default Into = Enabale NetBios Over TCP/IP

This worked pretty fine for me.
