Squid3 não starta

Pessoal:

Estou com o seguinte cenário:

virtual box com o ubuntu server 12.04 instalado e com a placa de rede em modo brigde

configurado o firewall e instalado o squid3(pro meu azar). até então não tinha instalado ele, mas somente com uma placa de rede em funcionamento o squid teria que funcionar normalmente como a versão anterior, mas não funcionou...

fiz os seguintes procedimentos:

criei o meu firewall:
#!/bin/bash

echo "1" > /proc/sys/net/ipv4/ip_forward

iptables -F
iptables -t nat -F
iptables -t mangle -F
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

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

baixei o squid:

apt-get install squid

porém veio o squid3, aí comecei a configurar normalmente com as políticas que eu sempre fiz uso e no squid.conf o diretório squid, modifiquei para o squid3. criei o diretório de cache do squid e apliquei o chmod 777. iniciei o squid e deu o primeiro problema:

root@squid:~# squid3 -k reconfigure

comentei a acl '0.0.0.0/0.0.0.0' e o problema sumiu:

daí apareceu mais um problema:

apliquei o comando reconfigure e o resultado foi esse:

alguém ppode me dizer onde errei no procedimento? e que erros são esses?

Obrigado pela ajuda.
