Squid 3.5.20 - cliente não acessa nada

gui.h3000
(usa CentOS)

Enviado em 17/05/2018 - 15:55h

Boa tarde a Todos, sou novo em Linux e estou subindo meu primeiro servidor Squid Proxy.
Bom aqui ja temos um rodando no CentOS 6 e como ele está começando a ficar desatualizado resolvi aprender e subir um no CentOS7 com o squid 3.5.20

Ainda estou no inicio e gostaria de saber se mesmo com algumas configuração eu ja posso acessar qualquer site na maquina cliente com configuração do proxy no browser.

O que eu percebi de diferente é quando está configurado com localhost ele me envia um erro quando dou o comando squid -z, mas quando coloco localnet ele aceita normal. isso é uma mudança devido a versão de 6 para o 7 ou do squid 2 para o squid 3.5.20?

segue abaixo meu squid.conf:

Agradeço qualquer ajuda, quero muito aprender.... obrigado.
