I just moved to a new place and internet is not setup yet so I'm using my phone's hotspot to get online. While developing a Python client-server program I found out that devices connected to Android hotspot cannot communicate with each other. When I ping one computer from another I get a "Destination host unreachable" message. This must be some sort of client isolation. Does anybody know how to turn it off? Using latest crDroid on Android 9.
[UPDATE] I run a few more ping tests and they seem pretty inconclusive. I got some hits but the results vary between 'Host unreachable', 'Request timed out' and various TTL times (6ms to 4000ms).
