Não consigo ssh ou nslookup desta máquina vm1 que tem o ip 192.168.56.2 de ferrari que tem o ip 172.45.20.3 . Eu não sei porque, mas eu sou capaz de ssh para o 192.168.56.2 da minha máquina host. O Iptables está desativado para fins de teste em 192.168.56.2 e 172.45.20.3 . Também posso realizar pesquisas inversas para 172.45.20.3 de vm1 , mas não posso fazer pesquisas de encaminhamento usando um nome de host.
