problemas com autenticação Squid

[X-LOGAN]

Olá pessoal
estou com o seguinte problema, meu squid esta rodando legal mas não habilita os acesso ao ip que estão no arquivo ip_liberados.txt, eu montei uma acl, mas não esta funcionando, olhem abaixo:

Squid.conf

http_port 3128

visible_hostname localhost

cache_mem 24 MB

cache_dir ufs /var/spool/squid 5120 64 64

dns_nameservers 200.204.0.10 200.204.0.138

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 to_localhost dst 127.0.0.0/8
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 488 # gss-http
acl Safe_ports port 591 # filemaker
acl Safe_ports port 777 # multiling http
acl CONNECT method CONNECT

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

Mude a ordem da regra coloque a ACL dos IPs em primeiros..
