I have the need to use SonicVPN Client to connect to my company's VPN. Unfortunately there are no ways to connect directly from Ubuntu. So I tried to set up a minimal Windows XP Virtual Machine in VirtualBox to run the SonicVPN Client on. All traffic that matches a specific network should be routed into that vbox. I have configured two network adapters. One Bridged and one Host-Only. The SonicVPN connection is shared over the Host-Only Adapter with "Windows internet sharing" (or so..).
Unfortunately I do not have a clue how to route the traffic correctly from Ubuntu.
I would be very happy, if someone had a tip for me.
