So I found out the hard way that the USB tether IP is 192.168.52.x and the WiFi addresses are 192.168.53.x.
My goal is to be able to access the USB tethered device (Raspberry Pi) from WiFi as if it's the same network.
If I had to specific ports, that'd be ok, but I'd like to avoid that if possible. I found this XDA post about reverse tethering (sharing a PC's internet connection over Android WiFi) which I think is really close to what I need, but in a different configuration.
Any help is greatly appreciated!
To add further clarification, let's say there are three devices: an Android phone, a Raspberry Pi, and a Macbook. The Raspberry Pi is tethered via USB to the phone. The Macbook is connected to the phone via WiFi. I want to connect to the Raspberry Pi from the Macbook.
the USB tether IP is 192.168.52.x and the WiFi addresses are 192.168.53.x.-- On some devices, its 192.168.42.x and 192.168.43.x respectively. You can always find it easily by looking at the gateway info in your OS.
