mpd as pppoe server problem

[Ganbold]

Hi,

I'm trying to configure mpd as a pppoe server in FreeBSD 5.3. However ADSL 
user can't log in to pppoe server.
Nothing happens on mpd console.

MX# mpd -f mpd.conf
Multi-link PPP for FreeBSD, by Archie L. Cobbs.
Based on iij-ppp, by Toshiharu OHNO.
mpd: pid 20841, version 3.18 (root at mx 10:43  7-Nov-2005)
[PPPoE] ppp node is "mpd20841-PPPoE"
[PPPoE] using interface ng0
mpd: accept encryption: not applicable
[PPPoE] the max MTU on type "pppoe" links is 1492
[PPPoE] exec: /sbin/ifconfig rl0 up
[PPPoE:PPPoE] [PPPoE] PPPoE server listening on rl0: for service "*"

Here is is my mpd.conf:

default:
         load pppoe
pppoe:
         new -i ng0 PPPoE PPPoE
         set bundle no multilink
         set bundle enable compression
         set bundle accept encryption
         set bundle max-logins 1
         set bundle enable radius-acct
         set bundle enable radius-auth
         set iface idle 0
         set iface disable on-demand
         set iface disable proxy-arp
         set iface enable tcpmssfix
         set iface mtu 1500
         set iface route default
         set link type pppoe
         set link mtu 1500
         set link no pap chap
         set link enable pap chap
         set link keep-alive 60 180
         set link max-redial -1
         set link mtu 1492
         set link latency 1
         set ccp yes mpp-e40
         set ccp yes mpp-e128
         set ccp yes mpp-stateless
         set pppoe iface rl0
         set pppoe service "*"
         set pppoe disable originate
         set pppoe enable incoming
         set ipcp ranges 192.168.5.50/32 192.168.5.128/32
         set ipcp dns x.x.x.x
         set ipcp yes vjcomp
         set ipcp no vjcomp
         set radius server x.x.x.x 1812 1813
         set radius timeout 10
         set radius config /etc/ppp/radius.conf
         set radius retries 3

What am I missing on above config? How can I debug mpd ? Because I don't 
see any logs coming.

thanks in advance,

Ganbold
