Basically, two systems create a tunnel.  That is, traffic from one to
the other is encapsulated (usually after being encrypted, that's the
private part) within a normal IP packet.  The packets are routed
normally, but only decapsulated at the other end.

So each system looks like it has a direct connection to the other.

You would need a tunnel endpoint at your work, then create tunnel end
points in you Linux and Windoze boxen.

I recommend OpenVPN.  Using certificates, you can put a server at your
work and then connect both your systems to work.  The OpenVPN
documents are very complete.  I've never gotten Windoze to work, but
then haven't tried too hard either.

I use this server/client with certificates all the time.  Makes life
very easy.  A number of my clients also use it and love it.
