hi,

someone know any functional configuration of squid in which to control the bandwidth of 2000 users, right now I'm working with dansguardian and squid but the truth is that I is functioning very well, I have many problems with viruses and what I want is to limit the bandwidth for certain users and limit the number of requests per user, which although many requests does not allow more than those in squid.
so far I have configured but the truth is I do not work if I put the funnel on l firewall, I need to put as proxy browsers, but not very functional because they are to much users and may not apply to everyone.
This is the configuration that I have so far:

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

#Local network definitions
acl miredlocal src 192.168.1.0/255.255.255.0
acl ACCOUNTSDEPT src 192.168.1.0/255.255.255.0

acl SSL_ports port 443

Can anyone help me please,
thanks.
