I have implemented max_user_ip acl with squid 2.6stable4 but users are able to browse the internet with a single account from multiple clients (those in the 172.16.0.0/23 class). This is my squid.conf:
authenticate_ip_ttl 3600 seconds acl all src 0.0.0.0/0.0.0.0 acl mynet src 172.16.0.0/23 acl generali src 10.180.0.0/16 acl concurrent_browsing max_user_ip -s 1 acl password proxy_auth_regex "/etc/squid/allowusers" acl password-generali proxy_auth_regex "/etc/squid/allowgenerali" http_access deny !password all http_access deny concurrent_browsing http_access allow password mynet http_access allow password-generali generali http_access deny all Hints?
