I have been following the same tuto as this one Sharing the Pi's WiFi connection through the Ethernet port.
I have a very similar setup. My phone hotspot providing the internet. My Pi connects with wlan0 to this hotspot, and shares it through eth0 (connected to a switch to share it with any connected device).
After following the previously mentioned tutorial, I managed to have:
- Internet on my Pi
- an IP attributed by the Pi to any connected devices to the switch.
However, those connected devices do not have the Internet. Any idea how to debug/what to check? I run line by line the script "bridge.sh", and everything was successful.
Thanks for your help in advance.
