Before going into main question, we do know that :

Now the question is :

"Is there a way to share the reverse-tethered internet (as we known connected via usb0 interface) via "Android WiFi Hotspot?"

To make it easier, here's the schema:

Schema of my setup (click image for larger variant)

*Additional Notes :

  • Actually I don't give a limit which version of the Android (so if it's just compatible in higher version e.g. 4.2, it's okay for me), but I prefer it works on 2.3.x (Gingerbread)

  • Some explanations of how to make APN (Infrastructure Mode) on Android (just like Wireless Router/[netsh wlan hostednetwork] on Windows 7/8) might be really helpful too.

  • And also some explanations about how to masquerade (internet sharing) between two interfaces in Android. (such as ICS in Windows or Masquerade/iptables thingy in Linux-based)

    @t0mm13b No. The OP doesn't want to know how to set up reverse tether, but how to share that connection to other devices.

    yeah, that's quite different that just reverse tether.. it's more advanced which, after you tether, you do "masquerade" sharing from usb0 into wlan0 and broadcast that as wifi hotspot. i understand that mistake that pretty "similar". please let LO this one. thanks in advance.

  • Btw: You might wish to take a look at Can we use an Android phone as a Wi-Fi repeater? and see how it applies to your case. Don't forget to let us know here then :)

I managed to make it work. Here is an "OSI-like" diagram of my setup, if it makes sense:

 ____________________   ______________________________    ____________
|   LinuxVM <----+  |  |                              |  |            |
|  VirtualBox    |  |  |                              |  |            |
| Windows7(host) |  |  | +--> AndroidPhone <-------+  |  | +-->Laptop |
|  (USB)         +-------+   (USB)  (wifi-HotSpot) +-------+   (wifi) |
|___________________|  |______________________________|  |____________|

The script is located at the XDA forum: http://forum.xda-developers.com/showpost.php?p=50236807&postcount=9

## 0.a. Connect android-phone to PC through USB.
## 0.b Enable Settings|...|Tethering 
##  (so that the device gets detected by the PC's kernel, you should see the following with 'dmsg':
##         [    3.976599] rndis_host 1-1:1.0 usb0: register 'rndis_host' at usb-0000:00:0b.0-1, RNDIS device, 4e:d5:8c:7b:4f:5a
## Enable Settings|...|Wifi-Hotspot

## Setup usb reverse-tethering.
#  from: http://forum.xda-developers.com/show....php?t=2287494
#  Yours device might be 'rndis0' or something else.  Check by just typing 'netcfg'.
netcfg usb0 dhcp
busybox route add default gw dev usb0

## Disable mobile-data.
busybox ifconfig rmnet_usb0

## Masquerade through USB.
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -F
iptables -t nat -A POSTROUTING -o usb0 -j MASQUERADE

## Set DNS (if neccessary, ie google's
setprop net.dns1 XX.YY.ZZ.WW
  • man.. the wait is over. this is the godlike answer XD Thanks a lot :)

    Excuse me, would you please tell me where to write and execute this script to allow wifi tethering while reverse tethering from usb? And please, is it a one way process or is it temporal?

  • 1. it's temporal. it breaks if any of interface down (offline) or restarted. 2. write this script via text editor and save it as <filename>.sh, execute it via terminal (emulator).

  • I able to access PC internet in android mobile using "AndroidTool.exe" tool now can anyone tell me what is next step to share the internet using wifi-HotSpot to other devices. above command tried still no success. Apr 26, 2016 at 9:23

I made a tool special for that use case: tetherspot

This script simplifies reverse USB tethering with WiFi hotspot on non-rooted Android devices

The main idea is to use

  • Gnirehtet on PC to start reverse USB tethering via VPN and adb
  • Proxy server on Android to route WiFi hotspot traffic to VPN
