PPtP over PPPoE (рвется соединение) [SOLVED]

Добрый день!

Столкнулся со следующей проблемой:
Необходимо организовать канал PPtP до удаленного BRAS. Сервер подключен к инету через PPPoE. Оба ppp-интерфейса прописаны в /etc/conf.d/net следующим образом:

config_eth1=("192.168.1.1 netmask 255.255.255.0 brd 192.168.1.255")
config_eth0=("null")

config_ppp0=( "ppp" )
link_ppp0="eth0"
plugins_ppp0=( "pppoe" )
username_ppp0='Логин1'
password_ppp0='Пароль1'
pppd_ppp0=(
"defaultroute"
# "usepeerdns"
"lock"
"updetach"
)
depend_ppp0() {
need net.eth0
}

config_ppp1=( "ppp" )
link_ppp1="pty 'pptp адрес_BRAS --nolaunchpppd --nobuffer'"

username_ppp1='логин2'
password_ppp1='пароль2'

pppd_ppp1=(
        lock
        nodeflate
        nobsdcomp
        persist
        mtu 1000
        logfile /var/log/pptp-client.log
)

depend_ppp1() {
        need net.ppp0
}

Соединение устанавливается и очень быстро рвется. В логах вот что:
- /var/log/pptp-client:

Modem hangup
Connection terminated.
Plugin passwordfd.so loaded.
Using interface ppp1
Connect: ppp1 <--> /dev/pts/1
LCP: timeout sending Config-Requests
Connection terminated.

- /var/log/messages
