Sadly, step by steps are only good for each company and what I use doesn't work for your company.
Maybe all you need to do is to FORWARD the VPN ports to your target machine. Again, I can't know this since at our office we don't use the standard VPN ports and a good IT staff won't go with the stock settings.
Sorry, but step by step isn't doable.

I work from my home and have one cable internet line that I use for work. I access my company network by VPN. I need some "very simple step-by-step instructions on how to set this up". My knowledge of network information is limited so please, keep this in mind. My company is not very keen on me using a router but having a second cable line installed doesn't make any sens to me.
