rfcomm_pppd and nat - trying to share internet with palm via bluetooth

[Peter Blowers]

Hi, ppp newbie here.
I'm trying to share my freebsd machine's internet connection with my 
palm via bluetooth.  The freebsd machine is connected via wired 
ethernet to a linksys wireless access point,  that is connected to my 
cable modem on the wan side.  The linksys AP is my gateway.

Bluetooth seems to be working fine. I can connect and ping the freebsd 
machine from my palm, but I can't get to the internet.
That is, I can't ping my ISP's DNS.  I thought 'nat enable yes' or 'set 
nat enable' would do it, but no luck.

I run the following on the freebsd machine:
/etc/rc.bluetooth start ubt0
sdpd
rfcomm_pppd -s -C 1 -l rfcomm-server

and in /etc/ppp/ppp.conf I have this:
rfcomm-server:
   set device /dev/cuaa1
   set cd off
   set dial
   set speed 115200
   set timeout 0
   nat enable yes
   set ifaddr 192.168.0.1/0 192.168.0.2/0
    enable dns
   add default HISADDR
   open
   disable pap
   deny pap
   disable chap
   deny chap

if I do this in ppp.conf instead:
   set ifaddr 10.10.0.2 10.10.0.201 255.255.255.0
where 10.10.0.2 is the wireless router(gateway), then the palm gets an 
ip of 10.10.0.201 just fine, and it can ping the freebsd machine 
(10.10.0.154) and the wireless router (10.10.0.2), but STILL can't get 
to the internet.
Also tried setting net.inet.ip.forwarding=1. No change.

Anyone have some suggestions?
thanks,
pete
