Olá, sou novo no Linux, mas sei da fama que o VOL tem na net.. Estou com um problema para configurar um Squid+IPTables no Fedora7.
Meu caso é que tenho um micro com 2 placas de rede (eth0 e eth1), onde a eth1 será minha conexão externa com internet e a eth0 será minha rede interna. Não estou conseguindo fazer o squid funcionar direito. Na hora que eu aponto a máquina para o squid e tento acessar algum site, a seguinte mensagem aparece no navegador:
"O seguinte erro foi encontrado:
* Falha na conexão
O sistema retornou:
(111) Connection refused
O host remoto (servidor) ou a rede pode estar indisponível. Por favor tente novamente. "
e o log do Squid fica assim:
""GET http://www.google.com.br/ HTTP/1.0" 503 1356 TCP_MISS:DIRECT"

Gostaria de saber se alguém pode me ajudar a resolver esse problema.

Obrigado!!
