Apenas recarreguei meu sistema operacional (Linux Mint 19) e estou tentando executar minha conexão VPN. Eu estou usando o mesmo arquivo de configuração .ovpn que eu usei com meu sistema operacional anterior (que funcionou bem), mas agora eu não consigo fazer o túnel para configurar corretamente (mesmo que ele diz que está conectado). um ip a mostra tun0 na seguinte configuração:
11: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN group default qlen 100
link/none
inet 10.8.0.14 peer 10.8.0.13/32 brd 10.8.0.14 scope global noprefixroute tun0

Normalmente, eu montaria meus compartilhamentos NFS no endereço do Servidor 10.8.0.1, mas a única coisa que posso fazer com esse endereço é fazer o ping dele. Há algo que eu esteja sentindo falta?
