 When a pand connection is established, /etc/bluetooth/pan/dev-up is executed, 
passing args "interface baddr" (for example /etc/bluetooth/pan/dev-up bnep0 
00:10:60:A2:3A:0B) . These are the scripts I use, you may find them usefull. 
On the client side:

fiam@americana 100% ~ $ cat /etc/bluetooth/pan/dev-up
#!/bin/bash

if [ "$2" = "00:10:60:A2:3A:0B" ]
then
        ifconfig $1 192.168.3.2
        if ! ifconfig | egrep "eth0|wlan0"
        then
                route add default gw 192.168.3.1
        fi
else
        mesg y
        echo "Pand connection to $2" | write fiam
        mesg n
fi

And on the server side:


fiam@ignition fiam $ cat /etc/bluetooth/pan/dev-up
#!/bin/bash

PAN_IFACE=pan0

if [ -z "$1" ]
then
        exit 1
fi

if ! ifconfig -a |grep ${PAN_IFACE} &> /dev/null
then
        brctl addbr ${PAN_IFACE}
        brctl setfd ${PAN_IFACE} 0
        brctl stp ${PAN_IFACE} disable
        ifconfig ${PAN_IFACE} 192.168.3.1
fi

if ! iptables -t nat -L -v | \
egrep "REDIRECT( )*tcp( )*--( )*${PAN_IFACE}
( )*any( )*anywhere( )*!192.168.232.0/24
( )*tcp( )*dpt:www( )*redir( )*ports( )*3128"
then
        iptables -t nat -A PREROUTING -i ${PAN_IFACE} -p tcp -d ! 
192.168.3.0/24 --dport 80 -j REDIRECT --to-port 3128
fi

brctl addif ${PAN_IFACE} $1
ifconfig $1 0.0.0.0

 Sorry for the ausence of comments, but I wrote these scripts yesterday and I 
hadn't time to comment them. If you need further explanations, just ask :)

Regards,
 Alberto
