[gepereir]

Boa tarde, galera estou implementando um proxy transparente no ubuntu com squid3 mas não ta rolando não sei mais o que faço ja procurei em tudo quando foi comunidade e as dicas são em vão, segue minha conf do squid e nada.

http_port 3128 intercept
#
#Default:
# acl all src all
#
#
# Recommended minimum configuration:
#
acl urlnegados url_regex -i "/etc/squid3/regras/proibidos"
acl ipsliberado src "/etc/squid3/regras/ipliberado"
acl manager proto cache_object
acl localhost src 127.0.0.1/32 ::1
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1
acl redesisepe src 172.18.1.0/24

#
# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed
#acl localnet src 10.0.0.0/8   # RFC1918 possible internal network
#acl localnet src 172.16.0.0/12   # RFC1918 possible internal network
#acl localnet src 192.168.0.0/16   # RFC1918 possible internal network
#acl localnet src fc00::/7       # RFC 4193 local private network range
#acl localnet src fe80::/10      # RFC 4291 link-local (directly plugged) machines

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

#
#Default:
# http_access deny all
#

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