Your problem is in understanding the problem.
The problem is that VNC requires a TCP/IP connection.

Under the circumstances you mentioned below, you connot 
make such a connection without "external" influences.
(In english: You need outside help)

Let's consider the case of accessing your home pc from the office:
Here a 2 questions for you to get answers for:
1) does you work network allow vnc connections to the internet?
VNC uses TCP port 5900, this is probably blocked by the firewalls at 
your office.

2) Does your ISP (Internet Service Provider, is the guy your buying you
internet connection from) allow VNC connections?   (Probably yes).

Both need to be YES, before a connection is possible.  Please check at
work if you can use VNC (make outgoing TCP Port 5900 connections).
