[squid-users] Bandwith limiting in specific ports

[Aristarchus]

Hi! Assume that i have 10 computers in a LAN and a 512 DSL. How can i limit the 
bandwith in a specific port? Lets say counterstrike port so that these 10 computers 
can play with little latency. Does this have to do with SOCKS? Is it possible to 
configure with squid?
