Problema com a conexão com PPTP VPN - Modem hangup

Question

Eu tenho seguinte problema com a conexão ao PPTP VPN no Ubuntu 14.04.

1. eu instalei o ppp e o ppp-linux

2. Eu configurei / etc / ppp / chap-secrets para seguir

   113.41.242.167\mark    PPTP    NaksOsP    *
   

3. Eu criei / etc / ppp / peers / vpn1 com os seguintes

   pty "pptp 113.41.242.167 --nolaunchpppd"                                    
   name 113.41.242.167\mark                                
   remotename PPTP                                
   require-mppe-128                                
   file /etc/ppp/options.pptp                                
   ipparam vpn1                                
   mru 1412                                
   mtu 1412 
   

4. Editei /etc/ppp/options.pptp para seguir

   lock
   noauth
   refuse-pap
   refuse-eap
   refuse-chap
   refuse-mschap-v2
   nobsdcomp
   nodeflate
   

5. Então eu corro sudo pon vpn1 sem resposta, então eu corri sudo pon vpn1 depuração despejo logfd 2 nodetach com a seguinte saída
