Do you have backupmenu installed where reinstall is easy over USB? You could also use backupmenu to access the filesystem over USB and remove or fix the script files.
anyways when you are back installed follow the link
https://wiki.maemo.org/Bluetooth_PAN
and start after it mentions Genwall which you do not really need, the scripts and iptables do it all.

Sharing your connection over bluetooth [n900]

Using udev to automatically setup internet connection sharing over bluetooth comes now.

A kernel with iptables support is needed,

Kernel Power is the recommended way to achieve this. see Kernel Power for installation details.

The default kernel with CSSU-thumb is also suitable.

Install the iptables package:

Code:

apt-get install iptables

create the following 2 files:

/etc/udev/rules.d/98-bnep0.rules:

Code:

ACTION=="add", SUBSYSTEM=="net",  KERNEL=="bnep0", RUN+="/etc/udev/bluenet.sh"

ACTION=="remove", SUBSYSTEM=="net",  KERNEL=="bnep0", RUN+="/etc/udev/bluenet.sh"

/etc/udev/bluenet.sh:

Code:

#! /bin/sh

if [ $ACTION = "add" ]; then 

        echo 1 > /proc/sys/net/ipv4/ip_forward

        iptables -t nat -A POSTROUTING ! -o lo -j MASQUERADE

        ifconfig bnep0 192.168.3.1

        ifconfig bnep0 up

        /usr/sbin/dnsmasq -I lo -z -a 192.168.3.1 -F 192.168.3.64,192.168.3.127 -x /var/run/dnsmasq.pid.bnep0

else

        iptables -t nat -D POSTROUTING ! -o lo -j MASQUERADE

        if [ -f /var/run/dnsmasq.pid.bnep0 ]; then

                DNSMASQ_PID=`cat /var/run/dnsmasq.pid.bnep0`

                rm -f /var/run/dnsmasq.pid.bnep0

                kill $DNSMASQ_PID

       fi

fi

then set /etc/udev/bluenet.sh as executible:

Code:

chmod +x /etc/udev/bluenet.sh

now whenever an authorised remote device makes a bluetooth pan (nap) connection iptables and dnsmasq are setup to allow that device access to the phones network. TODO: when no internet connection is active ask to set it up

I got bored tonight and thanks to this I managed to setup Bluetooth PAN, thank you biketool!
