Desculpa gente, mandei o arquivo de log errado o certo é:

[root@firewall ~]# tail -f /usr/local/squid/logs/cache.log

Foi mal. O log que mendei era do Squid 2.5 que tinha na máquina.

Bruno,

Pelo log parece que o squid não está rodando.

Outra coisa, no log aparece a versão 5 e no squid -v a versão
6 ??? ta estranho isso.

Verifique também as permissões dos diretórios e arquivos de
logs e cache do squid....

Srs,

Primeiramente gostaria de agradecer a lista pela ajuda. Porém não
resolveu o problema, o proxy transparente continua sem funcionar.
Depois de tantas alterações eis a situação atual:

Complementando o que o Fred comentou, aparentemente já está rodando um Squid
pois p log informa que já existe algum serviço utilizando a porta 3128.
Verifique através do "ps ax" se já não um existe um processo do squid e mate com
"kill" todos eles. Execute um: "find / -name squid" pois devem haver 2
executáveis em caminhos diferentes e execute um squid -v em cada um e remova o
2.5, por exemplo: /usr/loca/squid/bin/squid -v e /usr/sbin/squid -v

Depois tente inciar novamente.
