Web-Hosting from laptop to internet

I want to host my website from my laptop to the internet. I have done everything I could. I have done the following:

1. used xampp with port 80
2. made my system ip static
3. port forwarding in the router (port 80 to my laptop)
4. turned on the remote management on router
5. set apache and mysql private as well as public in firewall

but when I search with my public ip it's not showing my website. Please help me with the solution. I am in need of this.
