[MASOCH-L] Problemas rp-pppoe

["Tiago A. Peçanha"]

Pessoal,
Iniciei a instalação de um pppoe-server em cima do ubuntu 12.x, usando o 
rp-pppoe 3.11 + pppd 2.4.5.

Process: 12008 ?        S      0:00 /usr/sbin/pppoe-server -I eth1 -I 
eth1.100 -s -N 200 -C Som -L 177.x.x.x -p /etc/ppp/ippool

/var/log/syslog:

Freeradius log:
Sat Sep 29 13:05:55 2012 : Auth: Login OK: [rdne/1234] (from client 
pppoe04 port 0)

Rodando um debug mais preciso, pego as seguintes linhas também:
Sep 29 18:05:30 ubuntu pppd[24843]: CCP: timeout sending Config-Requests
Sep 29 18:05:30 ubuntu pppd[24843]: IPCP: timeout sending Config-Requests

Sep 29 18:05:33 ubuntu pppd[24843]: sent [LCP TermReq id=0x3 "No network 
protocols running"]*

Alguém já passou por problema semelhante? Alguma idéia?
