I am having problems as well. Its not working fine. I am guessing the problem is in the dhcp-server configuration, cause if I dont set my normal configuration as well as adding the bluetooth subnet it fails to start.
Also when I try to connect from the phone to the computer, it just stays there with the conecting screen. The interface is created but no internet acces.
Actually I am trying to get internet acces from my mobile phone using 3G to the computer. Is this posible using pand? or do I have to conect using the rcom mode?
