PPP server can assign IP addresses just fine without any DHCP. just put ppp/bluetooth clients on a separate subnet, i.e. in ppp.conf on bs something like (check with ppp(8) man page) server: ... other stuff ... set ifaddr 10.0.1.9 10.0.1.1-10.0.1.254 accept dns ... other stuff ... start rfcomm_pppd(8) with '-l server'. now all ppp/bluetooth clients should be of 10.0.1.0/24 subnet. make sure - all ppp/bluetooth clients have default route set to 10.0.1.1 - bs has gateway_enable="YES" - bs has valid entries in /ets/resolv.conf - all non-bluetooth clients should have route to ppp/bluetooth clients via bs, i.e. to reach 10.0.1.0/24 subnet packet should go to bs (10.0.0.9) > I have pppd running on bs.
