O squid esta bloqueando o acesso a intranet de um parceiro.
se eu digitar no navegador intranet.empresa.com.br aparece a tela solicitando usuario e senha. isso sem passar pelo proxy. seu passar pelo proxy a tela fica em branco.


não sei oque pode ser e gostaria de ajuda dos colegas.

segue meu script do squid.

Resolvi colocando a seguinte regra no firewall

$IPTABLES -t nat -I PREROUTING -s 192.168.0.0/24 -d intranet.opusxxxxx.com.br -p tcp --dport 80 -j ACCEPT
