I have one domain (website) and one home computer. On my home computer I installed software for mobile recharge. This system has a static IP.

So I send a recharge request (HTTP request) to my home computer using my website. The concept is: Every request is processed and sends a response to my website. But whenever I send the request, the home system port 80 is blocked.

My home system has no firewall enabled and no anti-virus software installed. So why does my port 80 appear to be blocked?

You need to tell your router to forward the request to your web server computer.
(This is called port forwarding; you need to forward port 80 to the IP of the server)

Note that many ISPs block incoming requests to port 80, so you may need to use a different port (eg, 81).

ok thanks how to set port forwarding in my router? – Karthik Sep 5 '11 at 19:27
That depends on the router. Go to the router's IP and explore, or Google the model name. – SLaks Sep 5 '11 at 19:31
