reverse tether - How to browse Internet in Samsung Galaxy Fit using Broadband in Windows 7?

I have a Samsung Galaxy Fit smartphone and want to browse the web on it using BroadBand connection (the one i use for my pc connection to Internet) in Windows 7.

Answer

From everything I have read about this topic, it is possible to do on a linux machine, but not with a windows machine. this could be because of something with ADB on windows, or the USB drivers for windows.

Here is the info (note that this reference was done with a Nexus One):

• Requirements:
  
  
  
  • Android 2.2 (or an older version with a root tethering app)
  
  
  • ADB from Android SDK, or a rooted Android 2.2 with terminal in root mode
  
  
  
  

STEP 1:
Device: Connect USB cable and activate USB Tethering. You should see on linux new network interface.

STEP 2:
On Linux Computer, setup a bridge:

• usb0 is the new network intreface


• 
  

  eth0 is the main interface connected to internet (or a gateway)

  
  

  $ sudo ifconfig eth0 0.0.0.0
  
  $ sudo ifconfig usb0 0.0.0.0
  $ sudo brctl addbr br0
  $ sudo brctl addif br0 eth0
  $ sudo brctl addif br0 usb0
  $ sudo ifconfig br0 up
  $ sudo dhclient br0

  
  

See Network Connection Bridge Help to setup bridges

STEP 3:

Setup usb0 interface of your phone. You have to options:

1. 
   

   From your computer, execute:

   
   

   ./adb shell netcfg usb0 dhcp

   
   


2. 
   

   Or in a root terminal on your phone, type:

   
   

   su netcfg usb0 dhcp

   
   

You should now be able to connect to Internet on your phone using your computer's Internet connection.

Try to do a ping www.google.com to be sure

STEP 4:

To shut down the reverse-tethering, first unbridge interfaces on your computer:

$ sudo ifconfig eth0 down
$ sudo ifconfig usb0 down
$ sudo ifconfig br0 down
$ sudo brctl delbr br0
$ sudo ifconfig eth0 up

$ sudo dhclient eth0

Then on your phone, uncheck the USB Tethering option
