Is it possible to have one Guest (Ubuntu) share another Guest's (Windows 7) VPN connection?

My work VPN runs Junos Pulse VPN client. Windows 10 is not supported, the Host Checker app will say the computer doesn't meet the requirements. OS is not supported. Windows 7, Mac, Android, and iOS devices are supported, but Windows 8 or 10 are not. So silly.

My thinking was to setup a new Guest VM for Windows 7. Load the VPN connection on Windows 7 then have my Ubuntu guest VM share the internet/vpn connection of the Windows 7 vm. Is this possible?

This week my company announced they now also support Cisco AnyConnect Secure Mobility Client, but i also have some issue that corporate VPN doesn't support Windows 10.

I might try getting one the VPNs to run under Ubuntu 12 or Ubuntu 14, but i am not sure about the company policy about Ubuntu. A lot of software developers must run Ubuntu to do the embedded firmware software development.

Any tips would be greatly appreciated!

Ignoring the vm aspect, it is difficult to share a VPN connection. In fact the software is often written to prevent it being shared. The whole point of a VPN is to have a secure one to one or point to point connection between two machines. It was designed to emulate a dialup or other physical connection by tunnelling through the Internet (which is cheaper and more flexible than a physical line). It was not designed to be routed.

I have two different systems sharing VPN connections. On my Mac I can run the corporate VPN and then use my Parallels Ubuntu VM to use the host Mac VPN connection. On another Windows 7 box, i have VirtualBox running corporate VPN and have my Ubuntu VM share the host Win 7 VPN. The issue is i have another system that must run Windows 10 but the corporate VPN won't allow Windows 10 yet. So i was hoping create a guest Windows 7 VM, run the corporate VPN there, then use the guest Ubuntu VM to use the Win 7 vpn connection. Maybe another way to do it is to have the Ubuntu guest use the Host internet connection and have the Host use the Win 7 Guest internet/vpn.
