Transparent proxy
添加一個群組叫 blocked_websites 並 deny 裡面設置的網站
/etc/squid/squid.conf
...
http_port 3128 transparent
...
# 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
# Only allow cachemgr access from localhost
http_access allow localhost manager
http_access deny manager
# 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 allow localnet
http_access allow localhost
acl blocked_websites dstdomain .msn.com .yahoo.com
http_access deny blocked_websites
http_access allow all
# And finally deny all other access to this proxy
# http_access deny all
...
最後記得把 deny all 註解掉，不然 host 會被斷網
最後在 iptables 內設定把從 80 port 進來的封包都通過 squid(3128)
