VPN-соединение itshidden.com прерывается и не будет переподключаться на Ubuntu Server 10.04

У меня есть сервер Ubuntu, который должен поддерживать соединение с VPN через itshidden.com через PPTP. Так или иначе, соединение прерывается один раз, и в / var / log / syslog появляются следующие строки:

Мой файл / etc / ppp / peers / itshidden:

pty "pptp vpn-pay.itshidden.com --nolaunchpppd" name itshidden remotename PPTP require-mppe-128 require-mschap-v2 file /etc/ppp/options.pptp ipparam itshidden defaultroute noipdefault persist maxfail 0 lcp-echo-failure 10 lcp-echo-interval 5 user "*********************" 

Какие-либо предложения?

Кроме того, параметры lcp-echo-fault / lcp-echo-interval не работают, так как я не вижу сброса ppp.
