и снова ВПН

Два дня уже мучаюсь не могу разобраться с впн.

Все было настроено и работало прекрасно , но пров поменял, диапазон
ip адресов которые выдавались по dhcp (было 10.66.X.X стало 10.100.X.X адрес, vpn 10.66.0.1 остался прежним) и добавил постоянный dns (было динамический) , и vpn перестал работать.

конфиги:
resolve.conf
nameserver 85.249.95.70

VLS
name roh6l21jnrjkbrtav81n
remotename VLS
mtu 1400
#noccp
#mru 1100
#debug
#dump
lock
nodetach
deflate 0
#defaultroute
file /etc/ppp/options.pptp
pty "pptp 10.66.0.1 --nolaunchpppd"

соединяюсь: pppd call VLS
pppd options in effect:

CCP: timeout sending Config-Requests и через минуты 2 соединения теряется.

прочитал вот здесь http://snezhnoe.dn.ua/download/linux/VPN/howto-diagnosis.phtml.html#ccp_timeout,
что проблема вызвана конфликтом между клиентом и сервером, но так и не понял что делать.

помогите плиз замучился уже.
