I would like to share my 4GLTE within my home network by tethering from my phone through USB. The reason is because I have other devices that need to communicate with each other without the need for Internet.
The following setup works without a problem: Android USB Tethering >Windows PC>Router WAN port
Now, I would like to do the same thing on the raspberry pi so it's as follows:
Android USB Tethering>Raspberry pi USB port---Raspverry pi eth0>Router WAN
The problem seems I don't know how I can share or simply allow traffic from USB to eth0 to pass through.
I followed a lot of tutorials and none of them worked.
The best I found that I understood involved installing bridging utils and setting up the br0 interface but that doesn't work either. I'm thinking the RPI3 has to dish out IPs.
Also, the router [Linksys 4200] does have a USB port and is running DD-WRT but I hear the USB support is for USB modems only. It doesn't work.
