Connection error in azure SQL server to google kubernetes through VPN

Hi
We have established connection from Azure SQL server to google kubernetes Nodes through Site to Site VPN.Now we can able to ping the azure SQL server and VM local IP address from google kubernetes container. But we cant able to access the azure SQL server database from google kubernetes node. We have contacted azure support team, they told “Azure sql server is based on FQDN (tesing.database.windows.net),so need to change the DNS settings in google cloud”. If we put nslookup tesing.database.windows.net getting google local IP address only. please check the below screenshot.

Need to change any DNS settings in google cloud?. Could you please check and guide me.

Regards,
Martin Jebaraj
