In theory you should be able to set up ICS on the host and share the VPN
connection to the guest (just like you would share an Internet connection).
You would link the host and guest through the loopback adapter. It works for
an Internet connection, but a VPN connection can be tricky to share.

    For an Internmet connection, it looks like this. The NIC in the guest is
set to the loopback adapter option and set to obtain its network config
automatically.
