I have a transparent squid cache 2.5.8+patches(pre9) and would like to stop the p2p traffic running through it. Does anyone have any ideas on how to do this? ACL's based on user agent? I'm already using the iptables patches (p2p) and have tried l7-filter, however it appears (V1.0) to have a memory allocation issue as it keeps using up all memory in the box (1G) and eventually killing the fw. Primarily it is FASTRACK and GNUTELLA that need to be stopped. Thanks, B.
