[FUG-BR] BLOQUEIO DE MSN

[Departamento de TI]

PREZADOS AMIGOS, BOA TARDE

ESTOU COM DIFICULDADES PARA BLOQUEAR O MARVADO MSN NA EMPRESA. EU TINHA
FEITO ALGUMAS CONFIGURAÇÕES QUE POR CERTO TEMPO RESOLVEU, MAS AGORA O
MSN CONSEGUIU SE CONECTAR NOVAMENTE.

JÁ FIZ TODOS OS PROCEDIMENTOS QUE ENCONTREI NA INTERNET, MAS MESMO ASSIM
O PROGRAMA WINDOWS LIVE MESSENGER CONSEGUE CONECTAR.

SE ALGUEM PUDER ME AJUDAR FICARIA IMENSAMENTE GRATO.

SEGUE CONFIGURAÇÃO DO MEU SQUID.CONF E LOGO DEPOIS A DO IPFW:
