I bet, if you enabled the Windows VPN server, then set up your phone to connect to your PC, VIA VPN I bet you'll be able to do everything you want to do that way. I'm going to install a second network card in my PC later this afternoon, and set up a second network and try this out as well. I'll post back here after supper.
EDIT: This is very easy to do with Windows7 and 10... as well as Android phones. Unsure about Apple products. Once i try it out, and it works, I'll help you to set it up.
