The computer is inside a company and only have internet access through proxy. I want the guest inside the VirtualBox to access the internet without changing anything in the guest. The host is Windows 10 Enterprise x64.
I know it is possible, I have done it with Proxifier
Proxifier allows network applications that do not support working through proxy servers to operate through a SOCKS or HTTPS proxy and chains.
But proxifier is not free and not very cheap for me.
I would love a solution that works as proxifier works but I need it just for the VirtualBox guests, so I think there might me a more specific solution for this case, any free solution for VirtualBox guest connections go through proxy will do.
