[Resolved] Windows Sandbox has NO Internet when the host is connected to a VPN
When the host is connected to a VPN, such as PPTP/L2TP and then I launch Windows Sandbox, I have no internet in it. please fix this. this problem existed on build 19H1 and it still exists on build 20...
HotCakeX not sure if you're still having this issue, but I was having a similar issue. Realized I had to allow LAN traffic with the VPN on. I use Windscribe and this provides the option to enable/disable LAN traffic. Sandbox traffic working after enabling (yeah, I feel dumb forgetting about this setting) and traffic is properly routed through my host's VPN.

I feel like a "network moron", but I'd like to understand WHY this works.
I'm finding a lot of references to this including "split tunneling" which I understood to mean allowing traffic to "route around" the VPN and access internet directly. All I want is the traffic from the sandbox to actually go through the VPN instead of null routing which is what seems to happen.
I'm not allowed to edit VPN configs, which is as it should be, and I definitely don't want to allow split tunneling. However, as a security analyst, I would like to be able to run things in the sandbox without disconnecting from VPN
