If I remember correctly, CIPE uses the networking headers to construct
its UDP packets. I can see CIPE being a bit of a big task to port; it's
a network driver, which means some of it has to run in kernel space. It
also means you have to create and bring up a network interface - which
may be tricky in Windows. In short, this is not going to be fun.

You may be far better off looking at a purely user-space tool like vtund,
which I've used on Unix. However, I still don't know how you'd cope with
bringing up what's essentially a PPP interface.
