Problems with Bluetooth LAN access

Hi! 
 
I meet a problem, while trying to access my LAN from iPaq 2210 through  
FreeBSD 5.3 box via Bluetooth. I have an Tekram-branded USB-BT dongle. 
This dongle is successfully recognized in OS and works: 
------------------------------------------------------------------ 
sanvean% /etc/rc.bluetooth start ubt0

I can see my iPaq from FreeBSD

And more, I can see all services, that iPaq provides.

Here is my pppd.conf file:

sanvean% cvery at /etc/ppp/ppp.conf

   enable dns

   deny pap 
   disable chap 
   deny chap 
------------------------------------------------------------------- 
 
Now, going to iPaq.... Well, I can see my FreeBSD box, i have discovered 
"LAN Access Using PPP" service and I am ready to use it. Let's go! 
Password? Forged about it, clear the fields and tap Ok. 
"Answering modem has disconnected", Ok! I have typed my FreeBSD login/password -  
Still no luck. Have killed 6 hours investigating this - still no luck. 
 
Now, my debug information:
