How to make Nokia E60 (E-Series) access Internet using USB cable and IP passthrough mode in Linux

Task

I want to access Internet from my Nokia mobile through the Linux computer, using the USB link cable provided, so what do I need is:

• Nokia E60 mobile :) I believe these instructions will also work on most other Series-60 (S60) Nokia phones.
• Linux box with 2.6 kernel (my case - 2.6.18)
• USB link cable provided with the phone

Lets assume we have next LAN configuration:

• On linux box: external IP address (eth0) - 87.124.26.127
• In Nokia mobile: access point configured for USB-cable connection with static IP address 10.0.0.2, default gateway 10.0.0.1 and don't forget to set two DNS servers (watch advanced settings when creating access point)

Linux setup

You need to build custom kernel at first. Here is what you need:

• Device Drivers -> USB support:
  • Support for host-side USB: Y. (not a module!)
  • USB network adapters:
    • Multi-purpose USB Networking framework: Y
    • Host for RNDIS devices: Y. (not a module!)

kernel: usb 2-1: new full speed USB device using uhci_hcd and address 10
kernel: usb 2-1: configuration #1 chosen from 1 choice
kernel: eth2: register 'rndis_host' at usb-0000:00:1d.0-1, RNDIS device, 00:15:2a:b6:be:28
        

• Put this line into your iptables configuration:
  • iptables -t nat -A POSTROUTING -s 10.0.0.0/24 -d ! 10.0.0.0/24 -j SNAT --to-source 87.124.26.127
    Don't forget to place your external IP here :)
• Probably you will need to enable FORWARD and INPUT connections from eth2 (or whatever interface name you will have after plugging in your mobile)

Now try to access Internet using your mobile using the interface (access point) you created by the name you gave it when creating.

Did you know that there is Safari browser in your phone? :) Check this javascript in your phone, it works just like in any other PC browser! :)
