Hello All, I am a new-be here. I am creating two acl's one for hosts and another with users. The config is given below acl AuthUser proxy_auth REQUIRED acl allowedHost src "/etc/squid/guard/privileged/testRule-ip" acl allowedUser proxy_auth "/etc/squid/guard/privileged/testRule-user" acl max_con maxconn 50 http_access deny allowedHost allowedUser max_con deny_info ERR_TOOMANY_CONN allowedHost allowedUser max_con http_reply_access allow allowedHost allowedUser http_access allow allowedHost allowedUser http_access allow AuthRequred http_reply_access allow all http_access deny all The value of acls are: allowedHost: 10.10.100.10, 10.10.100.20 allowedUser: test1, test2 Everything else is blocked. The problem is I want only allowedUser to access internet from allowedHost, But I am able to access internet from other hosts also using same user names. Thanks for help, Vipul Gupta
