Hi, I hope someone familiar with ip_queue can clarify the functioning of the ip_queue. I wrote a simple test program, what all it does read packets from the queue, hold a packet and accept it later. Here is the logic: read message from the ip_queue save message id read message from the ip_queue accept current message read message from the ip_queue accept current message read message from the ip_queue accept current message read message from the ip_queue accept current message read message from the ip_queue accept current message **accept saved message using the saved message id accept current message read message from the ip_queue accept current message When I accept the saved message, it just disappears. My question is, can we hold packets and accept them sometimes in the future? Thanks. MF Note: here is my iptable rules: iptables -t nat -A PREROUTING -p udp -s 192.168.82.140 -d 192.168.75.51 --dport 7862 -j DNAT --to 192.168.82.140:7862 iptables -t nat -A POSTROUTING -p udp -s 192.168.82.140 -d 192.168.82.140 --dport 7862 -j SNAT --to 192.168.75.51:7862 echo 1 > /proc/sys/net/ipv4/ip_forward iptables -A FORWARD -p udp -j QUEUE
