HowTo DUN without dund?

HI!

I was using dund for connecting my Palm via a Bluetooth dongle to the 
Internet.

This was working in Bluez 2.x and 3.23.

Now, with newer versions of 3.x, dund seems to be gone and I can't find 
information on how to enable and configure DUN without dund.

I was configuring the options for DUN in /etc/ppp/options.rfcomm0 like this:
# You usually need this if there is no PAP authentication
noauth
# do not use modem control lines we aren't using a real serial line
local
# do not determinate local ip from hostname
noipdefault
# usefull ARP proxing
proxyarp
# Your own IP Address and the IP Address of the remote system
192.168.0.2:192.168.0.47
# And the netmask
netmask 255.255.255.0
# dns
ms-dns 192.168.0.1
# this is required for the non standard microsoft PPP negotiation
connect "sleep 2; echo -n CLIENTSERVER"

And then I ran dund --listen.

Where can I put this stuff now? I found /etc/bluetooth/rfcomm.conf, but 
it does not seem to understand the keyword if the old config file.

Thanks!

Thomas
