me de uma luz no que eu estou errando

obrigado

opa consegui fazer funcionar so queria saber agora como eu fasso para meu firewall pingar para a internet e fazer meu apt-get funcionar

obrigado

Verifica as linhas de icmp, com relação ao apt-get, verifica se o firewall tem acesso as portas 80 e 21 (web e ftp)

Falow ...
