pptp problems

Please reply your message to klowd92 at hotmail.com

Im from israel. I use vpn over _cable_ (not dialing) to connect to the 
internet. works fine in windows.
On Freebsd 6.0. i installed pptpclient which uses pptpclient 1.7.0 sources, 
the newest version.

Problem description:
-I recieve a local ip from the cable company: 172.27.15.77 on sis0 
interface.
-I run pptpclient, seems to connect and creates a new device tun0 with a 
valid internet ip and gateway
-From here im still incapable of ping or resolving anything. Anything i try 
to resolve becomes 213.57.1.13 which is the ip for the cable company 
website. the name servers it uses are 192.168.101.101. which is the same as 
in windows, but on windows i am successful in resolving websites after i 
connect to vpn.
Also i cannot ping any valid ip over the internet. packets time out.
basically i cant connect or do anything.

I tried adding a route or changing default route, but usually when i do this 
i kill the pptp connection.

I can give you more info on the protocols of vpn in windows like PAP and 
SPAP but i dont htink thats the issue because i get valid ip on new device 
tun0, i just cant figure how to use it and connect through it without 
killing the pptp connection.

Here is all the info, i copied by hand because i dont have a link to the 
system.

problems.
