Could be multiple things, but what I can only assume is from what you've provided, is that you have a dynamic IP address. You forwarded the ports and stuff for your current IP, and recently your router gave you a new IP, thus disabling any forwarded ports. Two solutions exist, reforwarding your ports, or setting up a static IP address. I can help you with either, just PM me.
