[Bluez-users] NAT connection established but no data transport

[Bluez-users] NAT connection established but no data transport

[skrzypek-piotr]

First of all i would like to describe my situation. I`ve got two
computers: first one is a linux debian server (with kernel 2.4.27
pachted with grsecurity and bluez patch) and second is a notebook
running windows XP Professional. After many problems i`ve
succesfully established a NAT connection between the devices
(bluetake bt-007 using hciusb driver). The devices are paired and
connected but i can`t  notice the data transmittion. I tried to ping
one device from the other but i recive "timeout". I also tried
l2ping and it shows that connection id good (i`ve pinged a winmac
from linuxmac and it showed that data comes from linuxmac i don`t
know why but i think it means that connection is good). I`m not
really good in linux but i think it`s a problem with linux he can`t
recognise it as a network device. When i type ifconfig it shows
everything but not the bluetooth connection until i type ifconfig
bnep0. Maybe you can give me some advice how to make linux recognise
it and let it use wlan0 connection and eth0 connection. Please help
me cause i`m tryin to configure it for weeks.

Thanks, Pete

are you sure that you are using the latest -mh patch for your kernel?

do you have some firewall rules activated? Check the syslog for more
information and check with "hcidump -X" as root what goes over the
Bluetooth interface.
