I have been developing projects with Raspberry Pi 4. For the current project I am running a NextCloudPi server on it. I am able to access the server using my Internal IP. I want to access it using a public domain name or in other words through open Internet. My ISP does not allow port forwarding and static IP.
I tried Zerotier, which creates a VPN and I can access the CloudServer through the static IP assigned under VPN but the transfer speeds are really slow. Another issue is that I need to install it on all the devices through which I am going to access the CloudServer and ofcourse on the RPi4 itself.
Is there any other option that you guys probably have to access RPi4(Basically IOT devices) through Internet? Any suggestion would be greatly appreciated.
