Hello :-) That's my first mailist posting but I hope I'll get the basics soon. Please excuse my poor english. The problem I'm trying to solve is how to make ACL responding for a range of IPs (not the whole subnet). If I wanted to make the ACL responding for the whole subnet I would use CIDR or dotted notation like: acl mynetwork src 192.168.1.1/255.255.255.0 or acl mynetwork src 192.168.1.1/24 I want that acl 'mynetwork' to respond only for IPs 192.168.1.30 - 192.168.1.47 (for example). That is neither a subnetwork and can't be done via the upper examples. So can I use (from IP) (to IP) range in squid.conf and what is the exact syntaxis? I haven't seen anything like that in the online documentation, but that doesn't mean it doesn't exist :-) Greetings, Ivan Petrushev. ----------------------------------------------------------------- http://host.GBG.bg - лидер в Уеб Хостинг решения и регистрация на Домейн имена
