I've did this thing a while ago. Bluetooth router is a cool thing,
unfortunatelly only in theory.
To solve Your problem, look in /etc/bluetooth directory and check the
manual of bluez - there are a couple of pre-up and post-up scritps that
solve the problem.
I did manage to get bt router working but my usb dongle was cousing a
lot of problems - long story short - one dongle was not sufficient for
more than two simultanous connections.
