squid transparent olarakmı calısıyor
eğer cevap evet ise siz 80 porttan gelen istekleri 8080 yönlendirmişşinizdir muhtemelen o yuzden http://***** dediğinizde ulaşıyorsunuz
https=80 nolu portu kullanmaz o nedenle transparent olarak calısmaz
yapmanız gereken
açılışa bunları betik olarak hazırlayıp calıstırn
eth0 = internete çıkan ethernetiniz olsun
eth1= iç ağa bakan ethernetiniz oldugunu farz ederek alltakileri yazıyorum siz kendinize göre değiştirebilirsiniz
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
bu sayede sadece 80 değil tüm portları ic aga acmıs olursun
ardından
iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j DNAT --to 192.168.1.1:8080
bu sayedede http isteklerinizi squide yönlendirmiş olduk
artık sorunsuz kullanabiliyor olmalısınız

# TAG: http_access
# Allowing or Denying access based on defined access lists
#
# Access to the HTTP port:
# http_access allow|deny [!]aclname ...
#
# NOTE on default values:
#
# If there are no "access" lines present, the default is to deny
# the request.
#
# If none of the "access" lines cause a match, the default is the
# opposite of the last line in the list. If the last line was
# deny, the default is allow. Conversely, if the last line
# is allow, the default will be deny. For these reasons, it is a
# good idea to have an "deny all" or "allow all" entry at the end
# of your access lists to avoid potential confusion.
#
#Default:
# http_access allow all
#
#Recommended minimum configuration:
#
# Only allow cachemgr access from localhost
http_access allow manager localhost
http_access deny manager
# Deny requests to unknown ports
http_access deny !Safe_ports
# Deny CONNECT to other than 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
# to list your (internal) IP networks from where browsing should
# be allowed
#acl our_networks src 192.168.1.0/24 192.168.2.0/24
#http_access allow our_networks
# And finally deny all other access to this proxy
http_access allow localhost
# acl denge src 192.168.26.0/24 10.39.40.0/24
http_access allow denge
http_access deny all
