I just checked that, even if I am home and connect to my work place through VPN, and check for my IP address, it is the same as my home's IP address.
(for example, using Google, and search for
my ip, and Google will tell you your IP address).
So if I use my home computer, and check for the IP, and if I use my Macbook Pro which connected to my work's VPN (through my home wireless network), the IP are the same. I thought VPN works so that it is "as if I am at work", making it so that an intranet that I can't access at home become accessible because it is "as if I am at work", but then why and how can I show the IP as if I am at work?
