Hi,
i try to filter some traffic but some of the packets are miss :(
Linux version 2.6.3
iptables v1.2.9
udp traffic is about 4-6MByte per second
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
8502 8944K LOG udp -- eth1 * 0.0.0.0/0 0.0.0.0/0 udp dpt:22 LOG flags 0 level 4
8502 8944K DROP udp -- eth1 * 0.0.0.0/0 0.0.0.0/0 udp dpt:22

after this router i put other router and i have
tcpdump -n udp port 22 -c 200
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes
