possuo um servidor instalado squid3 efetuando o cache da porta 80 e porta 443, esta tudo funcionando, mas somente as paginas do google e gmail não acessam, n cosigo abrir de forma alguma.

realizei pesquisar e descobri que:

Google normalmente tenta se autenticar por uns dominios diferentes dele, que complica o negocio
Tipo, se vc tentar acessar https://www.google.com
ele vai te direcionar antes pra https://accounts.google.com

e o meu squid n esta conseguindo passar.




seria possivel relver esse problema? fazer o google passar pelo proxy
o tenho q liberar o google no iptables, para não ate o proxy? se sim como ficaria a regra do iptables.

segue rc.local
