L2TP works bad, PPTP doesn't work at all
 

Hi,
I'm using ubuntu 7.04 with a Thomson cable modem (eth0).
When I connect to my ISP with l2tp it works, yet disconnects
after several minutes (and it mesess up the resolve.conf file and I need to fix it after every connection).
So I tried configuring a connection using pon (pptp) and it passes veryfication yet no connection is made:
kfir@zalame:~$ sudo pon provider debug dump logfd 2 nodetach
pppd options in effect:
debug # (from command line)
nodetach # (from command line)
persist # (from /etc/ppp/peers/provider)
logfd 2 # (from command line)

dump # (from command line)
