Hi all, I've to configure Squid2 in order to ask for a password if a user go to an external address and no password have to be asked if the destination address is internal I've this rules: acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl to_localhost dst 127.0.0.0/8 http_access allow manager localhost http_access deny manager acl mynetwork src a.b.c.d/x acl to_mynetwork dst a.b.c.d/x external_acl_type NT_global_group %LOGIN c:/squid/libexec/win32_check_group.exe acl users1 external NT_global_group Users acl password proxy_auth REQUIRED http_access allow to_mynetwork users1 http_access allow password users1 http_access allow mynetwork http_access deny all but in this way squid require a password also if the dst address is in my network, what's the correct way to perform this task?
