Are you trying to take over your office machine from home, or your home
machine from the office?
Whichever way, you need to turn port-forwarding on on the router that is at
the other location than you are.  That is, if you're at home trying to take
over your office computer, you need to need to set port forwarding on the
router at the office.

Assuming both routers use NAT, and you want to take over your office machine
from home (but not the reverse), this is how your network should be
configured (substitute your own IP addresses)

Computer with VNC Server installed
192.168.0.17
|
|
Private LAN (office)
192.168.0.*
|
|
|
192.168.0.1 (LAN interface)
Office Router
port forwarding - 5800 and 5900 to 192.168.0.17
32.4.3.7 (WAN interface)
|
|
|
Internet
|
|
|
84.3.2.9 (WAN interface)
no port forwarding
Home Router
192.168.0.1 (LAN interface)
|
|
|
Private LAN (home)
192.168.0.*
|
|
Computer with VNC client
192.168.0.4

This setup should allow you to sit on the computer with VNC client, type in
32.4.3.7 into the viewer window, and connect to your VNC server.

If not, you should see if you can telnet to the server from the client (type
telnet 32.4.3.7 5800 from a command prompt) or at least ping the server from
the client (type ping 32.4.3.7)
