I just have another idea what might be the problem.

I had some machines which changed the eth device numbers of my networc cards 
after migrating from breezy to dapper. 
What was eth0 in breezy became eth1 in Dapper and so for the eth1 device in 
breezy which became eth0 in dapper.

To fix this you have to change the eth device number in the file 
 /etc/ppp/peers/dsl-provider
from 
 plugin rp-pppoe.so eth0
to 
 plugin rp-pppoe.so eth1

You also have to change the eth numbers in the file
 /etc/network/interfaces
from eth0 to eth1 and from eth1 to eth0

If you are using a firewall script you also have to change the device numbers 
there so that packets from your internal and external network are handeled 
propperly.

This is also for files of portsentry and others who use eth devices.
