Hi!! I am using iptables queuing concept to get the packets for my application.The applicaction is just doing simple dynamic nat if reqd..I change the dest ip in prerouting hook if reqd and the src ip i postrouting hook...This is working fine for first few pkts after i start my application..But after that i am getting segmentation fault...What is happening is one pkt after passing through and accepted by prerouting hook disappears..it gets lost..neither it enters FORWARD hook nor postrouting hook..and the next pkt gives me the SEGMENTATION FAULT ERROR .. CAn somebody tell me why is this happening???? Thanx in advance, Pooja ________________________________________________________________________ Missed your favourite TV serial last night?
