Expose a web application running from my internal network to public

Job ID: 33506544

Budget: ₹1,500 – ₹12,500 INR

Hi, I need a freelancer to help me expose a web application running from my internal network to public. Few points to note
1. This is a commercial product used by any person with or without network skill.
2. This small web application will be running as a server from user's home internet.
3. We can't do port forwarding as it is a commercial product and customer will not have skill set to add port forwarding in their router.
4. I have added UPNP in my code and it's successfully adding port in UPNP IGD but can't able to access the service with public IP.

I need a solution for exposing this service from internal network to public via public IP.
No use of any 3rd Party tool like ngrock.
