Here's hopefully a way to get your 6260 online via your Bluetooth dongle on Linux

0. Configure GnuBox
You will need to install gnubox_6670.sis on your phone.
This can be found at http://gnubox.dnsalias.org/gnubox/
It isn't my site, so I didn't hotlink it :)

Add a new Access Point called GnuBox. GnuBox is cAsEsEnSiTiVe.
Exit, without changing any further settings.

Start GnuBox.
Go to Options -> Install -> create records

Now exit GnuBox and start it again.

Go to Options -> 2box Bluetooth -> LAN Access server

If your screen is anything like mine, PortName will be BTCOMM::5

Ok, that is GnuBox set up - do not close it!


1. Setting up Linux
Create a file called /etc/ppp/peers/dun (I presume you have ppp installed)
Within that file, put in the following.


460800
debug # You can change this when it's working
10.0.0.1:10.0.0.2
ms-dns 194.168.4.10 # Change this to your ISP's DNS server
defaultroute
lock
crtscts


Next, start up the dialup networking daemon;


dund --encrypt --listen --persist call dun


Finally, use iptables to allow the 6260 to talk with the PC through NAT. (I also presume you have iptables installed!)


#!/bin/sh
IPTABLES=/sbin/iptables

# my outgoing connection
EXTIF="eth0"

echo "1" > /proc/sys/net/ipv4/ip_forward
echo "1" > /proc/sys/net/ipv4/ip_dynaddr
$IPTABLES -t nat -F
$IPTABLES -t nat -A POSTROUTING -o $EXTIF -j MASQUERADE



Your milage may vary and mine certainly did. I cannot get this fully working but I do not thing it is any fault of my own. I use cable instead of ADSL and I'm not sure if this has anything to do with it as such. Any suggestions for improvement are very welcome.

Best of luck.
