Thanks for your reply !!
I can access the real IP address 172.16.1.3 from INSIDE Zone. But I am unable to get through NATED IP from Public Internet. I am trying from different ISP and not the ISP where the ASA is connected to,

Hi all !!
I am able to get to the server now. Actually there may be some problem in the server itself which is Ubuntu Server. Now for testing we are using a Windows Desktop.
Now I am able to get to the Windows Desktop HTTP Server. I wonder what is the issue in Ubuntu Server.
Now there is an issue. I am unable to ping the server whereas I have configured ICMP inspection and allowed everything from outside using ACL.
If you all can please solve the Ping issue.
Regards..

Check the local firewall on the Ubuntu server. You can completely disable the ubuntu firewall using the command "ufw disable". Alternatively permit the required traffic. UFW examples:- https://help.ubuntu.com/community/UFW

Yes but I am able to ping and open the http server from INSIDE network. This implies that the firewall is not the issue.
I wonder why the server is behaving like that.

As per your direction, I will definitely check and disable it exclusively.
