Pessoal estou aqui configurando o iptables em um CentOS, estou montando um script e quando vou executá-lo em /usr/local/bin aparece a seguinte mensagem

iptables: No chain/target/match by that name

Alguém, sabe o que pode ser?

Segue o código

amigo não tem necessidade de voce declarar o "mangle" se vc nem vai usa-lo, ele é necessario para fazer marcação de pacotes para fazer balanceamento de carga de forma avançada....mais vou ver o que eu posso fazer por vc para encontrarr esse problema.
