I am testing how to use VPN connection in the Windows Sandbox environment (Windows 10 Version 1903).
I tested successfully with following configurations:
- Use UDP protocol
- Use NAT network
- Use Security/Privacy mode.
- Don't use Multiport feature.

After I set up with above configurations, I open Windows Sandbox.
Wait 2-3 minutes, I open the Network and Sharing Center in Windows Sandbox.
There is only one "Network" here. I open "Network" Status and configure with DNS's IP that I got from Windows Host Environment. After setting up, I can connect to PureVPN's IP and use PureVPN's DNS in Windows Sandbox Environment.

By the way, I also have a Dedicated DDoS IP address of PureVPN.

The problem here: I can not set up to use Dedicated DDoS IP/DNS in Windows Sandbox Environment.

Please develop PureVPN features so that users can use Dedicated IP or Dedicated DDoS IP in Windows Sandbox.
