Connecting from outside of network

[amartin@wayfieldfoods.com]

I am trying to use VNC o connect from my home to my computer at work.  I
am not on my works network, so entering the ip address is not enough to
connect like I can when I am actually at the office and use it to connect
to our various stores.  I have been unable to find how to connect from
home via the internet.  Is this possible?  Did I merely overlook something
or is this not in the programs capabilities?
