Como faço para configurar 3 placas de rede no Ubuntu e deixá-las pingar?

Question

Eu configurei uma Virtual Box no Ubuntu com 3 placas de rede. Como faço para configurar as 3 placas de rede para que eu possa pingar com sucesso entre 63 e 189 e 192?

Abaixo estão os detalhes da minha configuração:

ifconfig -a:
