My work computer has access to IP-restricted resources within my company. I need (well, want) access to those from home. How do I go about connecting to my work machine and using it as a pass-through, just so I can get to internal system resources? Is this what VPN is for? Is there some stupid simple way to setup a VPN server to do what I want?
A workaround may be to install LogMeIn Free on your work computer and effectively take control of it from your home computer to do what you need to do. Your work computer would need to remain switched on for this to work.
As quite rightly put by BBlake in the comment above, I would seek advice from your IT department before you do this or you could end up in a lot of trouble.
