When this happens the ports are no longer forwarded to that computer's IP address. But after restarting your computer it may use a different IP address. If you don't setup a static IP address the port forward will probably work the first time. When you setup port forwarding your router forwards ports to the IP address you specify. It's important to setup a static IP address if you are planning on forwarding ports.
