Regras de ACL

Pessoal estou com squid transparente funcionando, à principio.
Coloquei as seguintes regras de acl, mas não consigo navegar. Depois disso vou criar uma lista de sites proibidos, mas 1º toda rede tem q acessar a internet através do proxy. Tem alguma coisa errada nas permissões q dei?

acl all src 0.0.0.0/0.0.0.0
acl manager proto cache_object
acl localhost src 127.0.0.1/255.255.255.255
acl SSL_ports port 443 563
acl Safe_ports port 80 # http
acl Safe_ports port 21 # ftp
acl Safe_ports port 443 563 # https, snews
acl Safe_ports port 70 # gopher
acl Safe_ports port 210 # wais
acl Safe_ports port 1025-65535 # unregistered ports
acl Safe_ports port 280 # http-mgmt
acl Safe_ports port 488 # gss-http
acl Safe_ports port 591 # filemaker
acl Safe_ports port 777 # multiling http
acl CONNECT method CONNECT
acl rede_adm src 192.168.0.0

http_access allow manager localhost
http_access deny manager
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access deny all
http_access allow rede_adm


icp_access allow all
visible_hostname on
httpd_accel_host virtual
httpd_accel_port 80
httpd_accel_with_proxy on
httpd_accel_uses_host_header on

Valeu...
