PPTP client LCP errors

Hi guys,

I'm having a problem connection to a PPTP server using FreeBSD 5.2 and pptp 
linux 1.3.1. It works fine from a Debian box that's behind the FreeBSD 
gateway that I want to connect to the VPN but since FreeBSD's ppp is 
different than the one in Linux I cannot simply copy my config.

The server doesn't use mppe, on windows you have to disable LCP extensions to 
connect. The linux config is pretty straightforward but if you need that I 
can copy it too.

Here's what I have on FreeBSD:

/etc/ppp/ppp.conf
vpn:
# down lcp
# disable vjcomp
# disable MSCHAPv2
# disable mppe
# enable deflate pred1
# close lcp
# lcp-echo-interval 30
# lcp-echo-request 0 
# open lcp
# set openmode passive

# set openmode passive
# set stopped 3
# disable lqr
 
 set authname username
 set authkey password
 set timeout 0
 set ifaddr 0 0
 add 192.168.0.0/16 HISADDR
# set log Phase LCP Connect tun Warning Alert
 set log phase chat lcp ipcp ccp tun command
# alias enable yes
# noauth

I start it by doing ppp ip vpn.

and in /var/log/ppp.log when trying to connect I get:

The following part is repeated a few times and I think it's failing:
