Hi all, I have a problem with tracking UDP into the target QUEUE ... I know that UDP is non connected protocol, but I would like to get in the target QUEUE each first packet of a UDP "connection". I have 3 computers running linux. The architecture I use is the following : 192.168.0.1 ---------------- Ethernet Bridge ------------- 192.168.0.2 First I enter the rule "iptables -t nat -A PREROUTING -p udp -d 192.168.0.1 -m state --state NEW -j LOG" and I execute the command from 192.168.0.2 "nc -u 192.168.0.1 12345" and type some text. I have a look on the /var/log/syslog and there is only the first packet which is logged. I add the rule "iptables -t nat -A PREROUTING -p udp -d 192.168.0.1 -m state --state NEW -j QUEUE" which is exactly the same that the previous, but the target is QUEUE ... and I execute again the command from 192.168.0.2 "nc 192.168.0.1 12346" and type some text. And here is the problem : all the packets are logged into /var/log/syslog ... why ? I want netfilter to get only the first udp packet of a "session" into the target QUEUE ... It works with the target LOG ... why not with the target QUEUE ???? Thx for helping me Nicolas
