Boa Tarde.
Estou usando o Ubuntu 10.10 Desktop na VM, estou fazendo teste com o Squid e iptables, fiz a configuração do squid para bloquear sites, quando configuro o Browser com o proxy faz o bloqueio, fiz a configuração com o squid transparent e não fez o bloqueio dos sites, vou postar a regra e o squid.conf
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j \
