Hi, I would use the cbq (or htb, or any algo which is based on ip source) queuing in order to manage my bandwith (~ 12 Mbits fot 150 users). I can't make a rule in my firewall because my firewall doesn't know what is the ip source : he knows the proxy server ip. I have not seen the feature in squid - the only bandwith management I've seen is the delay pools -, is there any way to use a QOS based on ip source ? Or must I code the use of cbq ? Thanks, Grégoire Leroy
