Olá pessoal, montei um firewall que também é o gateway da rede, esta tudo configurado, maquinas clientes navegam sem problemas. não setei ainda as regras de bloqueio pois estou com problemas no squid. Estou com uma config basica, porém fui configurar um certificado ssl para proxy transparente. (squid 3.5) quando o Squid esta ativo esta bloqueando somente os protocolos Https o resto esta deixando passar, quando configuro no navegador cliente o proxy, ele bloqueia tudo, mas o https fica como se não tivesse conexão. Eu criei o certificado, porém não subiu. E o que eu quero é não precisar configurar o squid no navegador do cliente.
se eu desativo o squid , tudo funciona bem, quando ativo ai da algum errinhos.
