Estou enfrentando problemas ao tentar se conectar a um servidor windows vpn. No meu win 8 posso me conectar sem problemas; quando eu vou para o meu Ubuntu eu não consigo conectar-me à vpn. É o mesmo desktop, então o mesmo roteador.
Eu verifiquei as propriedades do roteador, ele tem a propriedade PPTP PassThrough habilitada.
Eu tentei várias opções pesquisando este e outros fóruns, por exemplo, eu apliquei todos esses itens, mas ainda o mesmo problema: Falha ao conectar-se ao servidor VPN PPTP no Ubuntu
Este é o meu / var / log / syslog:

Parece ser um problema com o GRE, mas sou novo no linux e não sei de nada em redes. Então, como posso resolver esse problema?
Ok, não se preocupe .. Eu fiz o melhor problema de resolução ..
Desinstale o PPP do Ubuntu Software Center e reinstale tudo com:
sudo apt-get -f install ppp network-manager-pptp pppconfig pppoeconf pptp-linux
Eu criei uma nova conexão VPN a partir do gui e configurei a opção MPPE como true. E funcionou bem! =)
Após desligar o computador e ligá-lo novamente no dia seguinte, ele está falhando novamente. Eu já reinstalei o ppp, mas o mesmo problema é enfrentado:
LCP: timeout sending Config-Requests
Qualquer pensamento?
