I understand that you are facing Internet connectivity issue after connecting to Azure VPN Gateway.
Please let me know if my understanding is incorrect and you are not using an Azure VPN Gateway.
- What authentication method are you using in your P2S configuration
- What is the SKU of the VPN Gateway you are using?
Thanks,
Kapil

2023-09-14T10:09:08.67+00:00 Can you please try the below,
- Explore Command (Windows Key + E)
- Right Click on "This PC", and select "Manage"
- Once Computer Management Opens, click "Device Manager"
- Under Network Adapters, uninstall all adapters starting with "WAN Miniport" - Right click, Uninstall
- Once you've uninstalled all, go to the menu and select "Scan for Hardware Changes" and those adapters will reinstall automatically without restarting.
In case the above did not help,
- Can you please remove the certificate and reinstall it?
- Can you use Azure VPN Client and not the inbuilt windows VPN and give this a try?
- In case you do not have the Azure VPN Client app
Cheers,
Kapil

2023-09-18T13:00:35.86+00:00 I think this is a DNS issue.
After connecting to Azure, I believe your DNS server is changing and thus you are losing internet connectivity
Please do the below and let me know the results
- Open CMD as admin and run nslookup www.google.com
- Please share the entire output of it.
- After this, connect to the VPN
- Again, Open CMD as admin and run nslookup www.google.com
- Please share the entire output of it.
- Now run nslookup www.google.com 8.8.8.8
- and share the output
- From the Azure VPN Client, share the "Routes learned" from the side panel.
Cheers,
Kapil
- Open CMD as admin and run nslookup www.google.com
