Ajudar a encaminhar tráfego através do VirtualBox
Estou tentando criar um ponto de acesso com um laptop WIN 10, um ponto de acesso Cisco Meraki MR-18 (AP), um Oracle VirtualBox 5.1.4 e um Ubuntu 16.04 LTS, funcionando como uma máquina virtual (VM). para atender as conexões sem fio de entrada. O laptop tem uma porta Ethernet física conectada ao AP MR-18 e uma conexão sem fio à Internet.
O VirtualBox cria o primeiro adaptador de rede e atribui endereço IP: 10.0.2.15/24 e Rota Padrão: 10.0.2.2/24 à interface do Ubuntu enps03. Esta é a conexão com o sistema operacional Windows 10 Host.
O segundo adaptador de rede VirtualBox é definido para estabelecer uma ponte entre a porta Ethernet física do laptop e a interface Ethernet virtual enps08 do segundo Ubuntu. Esta é a conexão com o AP MR-18.
Depois de criar essas duas conexões de rede no Ubuntu, nenhuma das duas interfaces Ethernet virtuais aparece no arquivo / etc / network / interfaces; no entanto, a primeira interface enp0s3 é UP e em execução e se comunicando com o sistema operacional host conforme ifconfig. A segunda interface virtual enp0s8 irá para CIMA e rodará assim que for declarada no arquivo de interfaces.

O dnsmasq do Ubuntu está configurado para atender as solicitações DHCP e DNS na segunda interface enp0s8, portanto, ele atribuirá um endereço IP e uma rota padrão ao AP MR-18.
