Hi, I got the time to use an equal setup like yours to test the drop rule. > NOTHING HAPPENS - Kazaa can download files again.... Well, i grabbed KaZaA lite (K++) today, installed it on my system (wich is connected to the internet trough a NATing router). IPP2P 0.5b was working perfectly fine, I used the following rule to test: iptables -t filter -I FORWARD 1 -p tcp -m ipp2p --kazaa -j DROP I could not download any more and iptables output looked like this: Chain FORWARD (policy ACCEPT 31525 packets, 1506K bytes) pkts bytes target prot opt in out source destination 11 4780 DROP tcp -- * * 0.0.0.0/0 0.0.0.0/0 ipp2p v0.5b --kazaa Removing the DROP rule let me download files again. So make sure that you're insmodding the right ipt_ipp2p.o and that your DROP-rule is in the appropriate place. I'll look at IMESH and Soulseek tomorrow.
