Eu tenho o gentoo linux rodando dentro de um host do VirtualBox Windows 10, que costumava funcionar até recentemente.
Basicamente, não importa qual protocolo eu tente usar, eu entendo que a rede é inacessível, para qualquer rede pública, exceto pelo fato de que pesquisas de DNS e ping funcionam. O firewall do Windows está completamente desativado. Como posso obter 'acesso à Internet' e tal trabalho?
Eu tenho 5 Vlans na minha rede, então eu defini qual deles deve ser usado usando:
VBoxManage modifyvm "Gentoo" --natbindip1 10.XXX.XXX.XXX , que parece ter feito o truque, caso contrário, nada funcionará.
Também tive que fazer VBoxManage modifyvm "Gentoo" --natdnshostresolver1 on , caso contrário, a resolução de DNS não funciona, mesmo quando eu configuro os servidores DNS corretos.
Se eu alterar VBoxManage modifyvm "Gentoo" --natdnshostresolver1 off , as pesquisas de DNS não funcionarão, no entanto, ainda posso pingar, mas o wget (como exemplo) ainda recebe Network is unreachable.
O erro que recebo ao tentar acessar qualquer tipo de recurso de rede é:
Connecting to www.mirrorservice.org|212.219.56.184|:80... failed: Network is unreachable.
O DNS / dhcp parece estar funcionando corretamente, como se define:
tim@vbox ~ $ cat /etc/resolv.conf
# Generated by dhcpcd from enp0s3.dhcp
# /etc/resolv.conf.head can replace this line
nameserver 10.0.2.3
# /etc/resolv.conf.tail can replace this line
tim@vbox ~ $ route -n

10.0.2.0 0.0.0.0 255.255.255.0 U 2 0 0 enp0s3
EDITAR :
Como um adicional de estranheza, se eu em vez disso ligar a uma vlan diferente, que usa um servidor proxy, e configurar o servidor proxy na VM - isso, então, tem conectividade total com a internet, como esperado. É quase como se, ao ligar-se a algumas das vlans, nem todo o tráfego fosse passado pela vlan.
Eu não posso usar a ponte de rede, já que não há um conjunto padrão de VLANs, e não quero tentar configurar em outra VLAN por causa da política de escritório;)
