Gente me ajude, meu script de firewall esta dando erros e não estou conseguindo matar a charada da coisa, toda vez que ele é ativo ele aparece os seguintes erros:
"itables v1.2.4: host/network orkut.com not found
try iptables -h or iptables --help for more information." esse erro aparece em toda lista de bloqueio,
a partir da linha # Bloqueios
segue meu firewall para analise. desde ja agradeço
