[FUG-BR] Squid 2.6 + PF

[Wesley Miranda]

Tive problemas com o squid 2.6.x em um cliente fazendo a mesma coisa que
voce, a solução foi baixar pra versão 2.5.x, outro detale utilizei ipfw,
segue o squid.conf e a regra.

Regra ipfw
/sbin/ipfw add 500 allow tcp from me to any dst-port 80
/sbin/ipfw add 600 fwd 127.0.0.1,8181 tcp from 192.168.17.0/24 to any
dst-port 80

OBS : http_access allow all > Voce pretende liberar sua proxy da rede
interna pra qualquer pessoa fora da rede utilizar ? O correto é Deny pra não
terem acesso externo.

Abraço.
