Whenever i access the VPN from my Laptop, internet is not working.

I unchecked use default gateway on remote network. Still not working.

Answer 1

Possible troubleshooting:

1

On Azure portal, click on Reset (is the same as restarting the server)

2

Make a telnet test on google.com, like:

telnet google.com 443

3

Try test internet access in other browser

4

Make sure if sites with ipv4 or ipv6 are having problems, if ipv6, see gateway config on this protocol.

5

Remove auto dectect proxy from browser before conect to the vpn client.

6

Make sure route print don't have a custom route as your default gateway

Hi Guys,

I've tested this issue.

Steps performed:

1. New Azure VPN config downloaded from the Azure Portal VPN Gateway P2S (doesn't work)
2. Checking of ipconfig /all , route print, tracert, nslookup, test-netconnection, telnet, wifi/wired interfaces settings (all checked, no issues)
3. The problem is somehow related to the the Microsoft EDGE web browser DNS settings. When open Microsoft EDGE -> Settings -> search for "dns" -> look for "Use secure DNS to specify how to lookup the network address for websites". By default there is a settings set "Use current service provider". To solve the case and have the internet connection while on Azure VPN select "Choose a service provider", click in the empty field below and select e.g. "Cloudflare (1.1.1.1)". It will appear as "https://chrome.cloudflare-dns.com/dns-query". Screens attached. Then reboot the web browser - Microsoft Edge - and the internet will start to work right away.

Security info: In this Cloudflare DNS is used to resolve your DNS queries. If you do not want to do that try with your own DNS servers or other DNS you prefer in this step.

NOTE: If this will help you feel free to leave short comment or just share this to other that have such issue.
