Eu tenho um servidor Ubuntu e o OpenVPN está funcionando bem lá. Eu posso traceroute / ping com sucesso muitos servidores. Também nesta máquina (com ou sem o OpenVPN rodando), o /etc/resolv.conf está pegando os servidores DNS sugeridos pelo meu modem / roteador que são apenas servidores OpenDNS.
Eu configurei o Kubuntu recentemente e configurei o OpenVPN, mas o que eu faço não consigo uma conexão externa. Traceroute / ping falha. Com ou sem o OpenVPN, meu /etc/resolv.conf sempre aponta para 127.0.1.1. Usando o NetworkManager, alterei as entradas DNS do IPv4 DNS para meu dispositivo Wi-Fi e tun0 para apontar para OpenDNS. Eu ainda não tenho conexão externa.
Eu pesquisei pela rede e descobri a necessidade de instalar o pacote network-manager-openvpn. Eu o instalei e, em seguida, importei meu arquivo de configuração OpenVPN (do servidor ubuntu). e ainda sem conexão. (mensagem de log na parte inferior). Meu provedor de VPN fornece apenas o certificado de CA.
Alguma idéia de como corrigir isso?
Obrigado
