我可以在本地访问该网站，但无法通过互联网访问它打开端口后

Question

I want to make my phone a Linux web server, by using the userLand application which gives you the ability to use ubuntu distribution on Andriod.

I already installed Django and ran my server on port 8080 since port 80 is busy (seems logical that android is using it)

and everything is good, it works when I try to access the website from another device on the local network.

so I proceeded to the next step which is making the website accessible from all over the internet then I found that you need to make a port forwarding on the router to allow devices from outside the local network to access a device in the localnetwork.

I followed the following steps:

1. made the phone's IP static locally
2. added the configuration needed for the port forwarding (phone's ip, port 8080, etc... )
3. found the public IP for my phone and used it and with port 8080

it is still not working: I can access the website locally but can't access it through the internet.

I tried another method by using an already working server from the "AWebServer" application on google play

but still the same problem.

I tried temporarily to disable the firewall on the router but still the same problem

and finally, I tried to open the port on my laptop with OS: Windows 10 instead of the phone OS: Android, and checked with port checker but the port is closed and still the same problem.

I have been trying to solve this for a whole day)), I would be very happy if someone helped me.

thanks

Answer 1

Your ISP might have put you under a NAT, in that case port forwarding might still not work.

Your best bet is to use some sort of SSH Tunnels.

You can try with ngrok .

This will give you a URL to access your application from public internet.
