I have a running home server (using Windows 7), and inside the LAN I can surf the site. I have made the necessary changes in the firewall and forwarding the port in router.
Sadly, when I try to get the site from outside the LAN by the external ip (and the port I'm forwarding), I can't reach the site. like it doesn't exist.
I'm pretty sure I did the forwarding right, because when I try to surf the web from a computer in the LAN, and use the router external ip (and the port), I get my website.
All the guides stops here. I have search the web for days - and nothing.
I know it doesn't matter, but I tried apache2.4 , tomcat, xampp and even built my own server with Java - none of them worked outside of the LAN

More than likely, your ISP is blocking port 80. Port 80 is the standard port used for the web. ISPs will block port 80, saying that web hosting is a business level service and will charge your more. Try changing the port in your server to 8080, as well as change your port forwarding. Then connect to your server in a browser with :8080 appended to the end. Once that is done, replace the following with your external IP address and enter it in your browser .
You can always check with your ISP to see if they are blocking port 80. If they are, you can simply use a different port like 8080, or pay for the higher level of service.
1Does your internet access point (cable modem, dsl modem) also act as your router, or do you have a second device after that device such as a wireless router? In the case you have two devices it is possible that your setup is actually requiring port forwarding on the external device (the modem) and the internal device (the wireless router), or better yet, to place the external device into a bridge mode that enables your purchased router to be the outermost device on the network as far as routing is concerned.
