Hy ,

I had similar problems and I solved them this way:

1.Kernel must be compiled with the option tunneling  
2.Before running pptp client modules new_tunnel and ipip must be inserted
in the kernel.
3.The server side must have dial-in permision granted to the account that
you use( This is mostly the problem when message like outgoing call
established... and client connection established and then closing
whithout any explanations...)
4.And if possible checking the authentification methods on the NT server
side .

What is strange is that it is using ppp0. I assume that your ppp conection
to your ISP must be on ppp0. The pptp connection then takes ppp1,ppp2..

			I hope this helps a bit.
