Block Gnutella

To block Gnutella, you should close 6346 6347 udp tcp

I assume the network address is 202.0.0.0/28

access-list 101 deny tcp 202.0.0.0 0.0.0.15 any eq 6346 log
access-list 101 deny udp 202.0.0.0 0.0.0.15 any eq 6346 log
access-list 101 deny tcp 202.0.0.0 0.0.0.15 any eq 6347 log
access-list 101 deny udp 202.0.0.0 0.0.0.15 any eq 6347 log

Block Kazaa

access-list 101 deny tcp 202.0.0.0 0.0.0.15 any eq 1214 log
access-list 101 deny udp 202.0.0.0 0.0.0.15 any eq 1214 log

Block ICQ

access-list 100 deny tcp 202.144.158.192 0.0.0.255 any eq 5190 log
access-list 100 deny udp 202.144.158.192 0.0.0.255 any eq 5190 log

Block Napster

access-list 100 deny tcp 202.144.158.192 0.0.0.255 any eq 8888 log
access-list 100 deny udp 202.144.158.192 0.0.0.255 any eq 8888 log

Notice: I don't guarantee all the services above. Some may not be able to block now or the future.
