On the Model 4 when I connect to 10.10.10.10 from my Android mobile I can not only access RACHEL-Kolibri local page but can also access sites on the internet from my phone browser through it. On the Model 3 when I connect to the WiFi it warns “Your device is connecting to RACHEL-Pi. However this network may not provide Internet access”. And sure enough it doesn’t allow me to browse any sites. But the RPi are all getting a DHCP address from my router over Ethernet - this one is 192.168.1.40 for example. And I can ping sites on the Internet from a terminal session on the server.
It seems that on the Model 3 it is just not routing through from the WiFi to the ethernet connection.
I should say that it is probably not a real issue for us since most Malawi schools are not currently connected to the Internet. They could be in future, I guess.
