Minha VPN continua desconectando. Estou usando o Ubuntu 14.04 64bit HP workstation.
A conexão VPN simplesmente desaparece após um período de tempo aleatório, não importando se estou usando ou não. Eu tentei algumas coisas que eu descobri aqui ou em alguns fóruns, mas continua a falhar. Eu tentei desativar qualquer tipo de compactação.
aqui está o log de /var/log/syslog
