Proxy comum e transparente [RESOLVIDO]

olá a todos,

Tenho lido a respeito do Squid sobre o proxy transparente, mas pelo que entendi, ele tem seus prós e contras. Ele seria mais fácil de configurar, obrigando os clientes a acessar a porta 80, porém para casos de outros protocolos, como FTP e outros, que utilizam outras portas, como fazer esse bloqueio? Como bloquear por exemplo o webmessenger, dentro do e-mail do Hotmail ou o Gtalk, dentro do Gmail? Existe como bloquear esses serviços pelo servidor Squid?

Tenho outra pergunta: Vi no site do Squid Cache que o Debian já está usando o pacote "squid3" ao invés de "squid" e que se instala usando o comando "aptitude" ao invés de "apt-get". É obrigatório instalar a versão 3 dele ou pode ser pelo comando "apt-get install squid"?

Obrigado!
