Estu tentando implantar o Squid com suporte a tproxy em nossa rede.
Meu ambiente é:
Arch Linux
kernel: 2.6.30
iptables: 1.4.6
ebtables: 2.0.9
squid: 3.1.0.14
Arquitetura da rede (modo bridge)
eth1: 0.0.0.0
eth2: 0.0.0.0
br0: 172.16.2.3/12
route: 172.16.0.1
Firewall:
cd /proc/sys/net/bridge/
for i in *
do
echo 0 > $i
done
unset i

Meus problemas:
Navegação lenta, ou seja, tento abrir a pagina pelo navegador mas o mesmo somente abre caso entre no servidor com o Squid + TProxy instalado e pingo para o site, caso contrário o mesmo dá conexão recusada, com erro MISS/500.
Fiz testes com o Prxy Lusca mas o mesmo se comportou da mesma maneira.
Alguem já passou por estas situações ?
