635 http_access deny !Safe_ports
636 # Deny CONNECT to other than SSL ports
637 http_access allow CONNECT !SSL_ports
http_access allow localnet

# And finally deny all other access to this proxy
http_access deny all

valeu galera

é proxy transparent ?
se for ta faltando regra no teu squid!
Qual a versão do Squid ? 2.7 ? 3.0 ?
para abrir sites 443, use:
iptables -A FORWARD -i eth1 -p tcp --dport 443 -j ACCEPT
lembrando que eth1 é a placa onde as maquinas conectam no servidor...
transforme seu squid em transparent ....
assim:
http_port 3128 transparent

outra pergunta!
porque esta usando o squid se não habilitou cache, controle de acesso, autenticação... enfim, sem isso o squid não serve de nada, somente enfeite...

esqueci de colocar a versão do squid é 2.7 stable3

O erro pode estar aqui

#http_access allow CONNECT !SSL_ports

o "!" diz para excluir o que vem após ele. Tipo "Conecte-se a 'fulado' menos a SSL_ports". Troque o "allow" por "deny" ou tire o "!", aí vc estará negando a conexão e tudo que não estiver incluido na regra SSL_ports e permitindo apenas o que estiver em SSL_ports. Entendeu?
E tente também colocar as portas da regra Safe_ports na mesma linha, eu tive problemas em criar multiplas regras com o mesmo nome.

Eu tb liberei a porta 443 no firewall da seguinte forma:

#iptables -A FORWARD -s 192.168.0.0/24 -p tcp --destination-port 443 -j ACCEPT
#iptables -A OUTPUT -s 192.168.0.0/24 -p tcp --destination-port 443 -j ACCEPT

Troque o IP e mascara pelo de sua rede local.
