o que tem de errado pro squid nao ta funcionando em modo transparente ?

posta tuas regras de redirect?

iptables -t nat -A PREROUTING -s 0/0 -p tcp --dport 80 -j REDIRECT --to-port 3128
iptables -t nat -A PREROUTING -s 0/0 -p udp --dport 80 -j REDIRECT --to-port 3128

é isso ?

as minhas estão assim ,,, -i interface da rede que vi utilisar o proxy..

iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 3128
iptables -t nat -A PREROUTING -i eth1 -p udp --dport 80 -j REDIRECT --to-port 3128

tenta colocar essas ai ,, se naum direcionar,,cola pra gente o arquivo cache.log /var/log/squid/cache.log ........

faz o seguinte ,,, aparentemente tah tudo ok ,,, mas pra podermos analizar melhor oq esta se passando faz o seguinte ,,, deleta os arquivos , store.log , cache.log e access.log, deleta o cache , para todos os processos de squid q tem rodando ,,, squid -k kill ,,, e inicia novamente,,,,
squid -z
squid -Ds
depois disso roda manualmente no shell as linhas de iptables e analiza no teu access.log se tah havendo solicitacoes de web nele.... aproveita e coloca novamente o cache.log novo q ele vai criar pra mim dar uma analizada...........

fiz isso e que estranho o access.log nao tem nada
e olha o cache.log

eu alterei o http_port para 10.0.1.1:3128
http_port 10.0.2.2:3128
que na verdade sao os ips da respectivas eth0 e eth1 e acho que agora foi.
