Thanks
Finally I got a solution
I had to do some setting in my router
In the router I looked for Virtual Server
There I did setting for DMZ host
In DMZ HOST i mentioned the static IP of my PC in local netowork and saved
Finally I got it available on Internet.
Here I like to mention that this I did with my Dynamic IP. We can do it with STATIC IP.
It is worth to mention that there is always a security threat.
