Apache not responding on port 80 after forwarding port?

view story

http://unix.stackexchange.com – I'm trying to set up a web server for my first time. I'm running Ubuntu 12.04.1 and i've installed LAMP. I have also set up a static IP for the server, and reserved it in the router settings. So far so good. Now to the problem. I forwarded port 80 to the servers IP address, but the server is not responding to any connections. If i try to access the public IP through a webbrowser when the port is NOT forwarded, i get an error saying "Could not connect to host". If i do forward the port i get a timeout error. Correct me if i'm wrong, but that should mean the port is being forwarde (HowTos)
