Jamie,
If you're using port forwarding, you need to do one of these things:
1. Use a static IP address on your computer, not DHCP. Do this if you've got a desktop pc, or a laptop and dont use any other networks.
2. Setup the DHCP service on the router to always assign your computer with the same IP address. Do this is you've got a laptop and you use other networks. You'll need to feed your router the MAC address of your computers network card. You can get this from running IPCONFIG from a cmd window.
