In addition to "enabling" port 80, you need to "forward" it to your server. This means reconfiguring your router. Be sure you know what you're doing as opening and forwarding ports can make your network vulnerable to intrusion.

For this to work reliably your server needs to have a fixed IP address e.g. 192.168.1.10 otherwise each time your server is rebooted it will get a different IP address and the router won't know where to forward port 80 requests from the outside world.
