Fedora Networking :: Setting Up Static IP And Vnc Viewer Behind A Router

I have an old pc that I would like to use as a headless server for my music, files, etc that I can access at work and other places outside of my network. I'm a complete noob in this department so please excuse my overwhelming ignorance. The only thing I've managed to succeed at was installing fedora 13. Two things in particular are giving me trouble: 1.)setting up my router and fedora box so that it has a static ip address and 2.)connecting to the fedora box via vncviewer on my laptop.

HERE ARE SOME QUICK SPECS THE DEVICES INVOVLED:
Fedora Box: Intel Pentium 4 2.66GHz, 1GB ram, Fedora 13
Laptop: Toshiba Satellite A505, Intel Core 2 Duo T6600 2.20GHz, 4GB ram, Windows 7 Home Premium 64-bit
Router: D-Link WBR-1310
ISP: Comcast (cable)

HERE'S WHAT I'VE DONE SO FAR:
Setting Static IP
On the fedora 13 box:
1.)Went to Network Connections and added a new connection
2.)Copied mac address from the default connection
3.)On IPv4 tab, added new address: 192.168.0.200 (this is out of the range which my router will assign automatically) netmask 255.255.255.0, set gateway to 198.168.0.1(router's ip on the network)

When I connect to this new connection web pages don't load, etc. but when I'm on the default connection I have no problems.

Connecting With Vnc Viewer
On the fedora 13 box:
1.)System -> Preferences -> Remote Desktop
2.)Under Sharing I checked "Allow other users to view your desktop" and "Allow other users to control your desktop"
3.)Under Security I unchecked "Ask you for confirmation", checked "Require the user to enter this password", and specified a password

On the router
1.)Set up port forwarding for port 5900, TCP only, to the ip address of the fedora box.

On the laptop
1.)Installed VNCViewer
2.)Went to whatsmyip(dot)org to get ip address of router
3.)Tried to connect to that address, port 5900 (ex. ##.##.##.###::5900)
4.)Connection times out everytime.
