Estou tentando usar o proxy transparente, mas não esta funcionando da forma que deveria.
todos os sites https é que não abrem, EX: gmail.com, orkut.com. E tambem o msn que usa as portas 1863 e 443 não funciona. Eu sinceramente ja virei a noite tentando entender o por que com o proxy default eu consigo acessar ao gmail e no transparente ele não funciona. A importante o msn não funciona nem no proxy default e nem no transparente tb. Agradeço toda a ajuda, deem uma analizada no squid e no iptables. Segue o meu squid. conf e meu firewall teste:

Galera estou com um outro problema aqui agora. Quando ativo o squid, não consigo abrir o gmail.com e nem o msn. Não tenho nenhuma lista no squid de bloqueio, e quando eu estou acessando com o squid parado tudo funciona. Deixa eu explicar melhor os problemas:
1- Proxy Default

Acesso ao gmail, mais não acesso ao msn.

2- Proxy Transparente

Não acesso ao msn nem ao gmail.com

Eu sinceramente não consigo entender. Estou aqui tentando resolver isso mesmo assim. valeu ae.
