Estou trocando de servidor, do Ubuntu 14.04 para o 18.04, mas o openvpn não está funcionando, consigo conectar e pingar o IP da interface tun0 mas não consigo acessar a rede interna. o Openvpn funcionava corretamente no servidor antigo com o Openvpn 2.3.2. Não sei o que pode ser.
Ps:O ip_forward já esta = 1.
Segue os arquivos de configuração do servidor e cliente e logs.

Bateu uma dúvida agora: quando vc diz que não acessa a rede interna, vc quer dizer a rede do cliente, ou do servidor?

Ah. Eu estava entendendo que vc estava parando de enxergar a rede do cliente, quando conectava.
Lá em cima, vc disse que a regra de rota foi desativada pq passou a dar erro. Me parece que é isso que está faltando, uma regra pra ensinar o cliente da rede do servidor. Veja se a sintaxe da regra mudou, ou se há alguma outra forma (de preferência que só ative quando a conexão ativar) de ensinar essa rota pro cliente.
