Question : Port forwarding

Hi,
   I have a modem/router in my house (beetel), which has IP address 192.168.1.1. It acts as DHCP server and I get IP address 192.168.1.3 for my laptop.

I have set up Apache 2 server in my laptop, and I am able to access the web site as either: http://192.168.1.3 or http://localhost

Now, what I need is, I should be able to access this web page from outside my LAN network, using my public IP. How do I do this?
