Hi everyone, thanks again for all the help ! I have many subnets: 10.10.1.0/24 10.10.2.0/24 10.10.3.0/24 10.10.4.0/24 . . . 10.10.200.0/24 and I want to control the bandwidth of each one. I think this could be: acl clients src "/etc/squid3/net" # In this file I have all the subnets delay_pools 1 delay_class 1 3 delay_parameters 1 491520/491520 16384/16384 -1/-1 delay_access 1 allow clients Here I just want to restrict the /24 subnet, I don't care the individual host, and restrict each one at 16 Kbps, not all to 16 Kbps. With this conf I make this ?
