Squid 3.2.13 FC18 não bloqueia ACL

Boa noite pessoal.

Estou apanhando do squid 3.2.13.

O arquivo de conf da versao 2.6 não funciona de jeito nenhum.

Entao resolvi realizar a configuração apartir do exemplo mesmo.

Resolvi começar simples e depois ir adicionando mais funcionalidades.

A topologia é a seguinte:

A maquina onde o squid esta instalado tem 2 interfaces de rede, cada uma em uma subnet diferente (8/24).

Esta maquina tb faz o compartilhamento do link.

Tentei criar apenas 1 acl e deixa-la como deny, mas o bloqueio nao funciona nem a pau.

Segue:

#
# Recommended minimum configuration:
#

# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed

acl localnet src 192.168.0.0/24

acl SSL_ports port 443
acl Safe_ports port 80 # http
acl Safe_ports port 21 # ftp
acl Safe_ports port 443 # https
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

#
# Recommended minimum Access Permission configuration:
#
# Only allow cachemgr access from localhost
http_access allow localhost manager
http_access deny manager

# Deny requests to certain unsafe ports
http_access deny !Safe_ports

# Deny CONNECT to other than secure SSL ports
http_access deny CONNECT !SSL_ports

# We strongly recommend the following be uncommented to protect innocent
# web applications running on the proxy server who think the only
# one who can access services on "localhost" is a local user
http_access deny to_localhost

#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#

# Example rule allowing access from your local networks.
# Adapt localnet in the ACL section to list your (internal) IP networks
# from where browsing should be allowed

http_access deny localnet
http_access deny localhost

#http_access deny localnet

# And finally deny all other access to this proxy
http_access deny all

# Squid normally listens to port 3128
http_port 3128 transparent

# Uncomment and adjust the following to add a disk cache directory.
cache_dir ufs /var/spool/squid 100 16 256

# Leave coredumps in the first cache dir
coredump_dir /var/spool/squid

# Add any of your own refresh_pattern entries above these.
refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern -i (/cgi-bin/|\?) 0 0% 0
refresh_pattern . 0 20% 4320

Nao vejo como pode ser mais simples que isso ... o problema é que mesmo depois de reiniciar o servico, o bloqueio nao é efetuado.

alguma dica ??
