I can't find how this could have happened, please enable CONFIG_NETFILTER_DEBUG, the DPRINTK defines in ip_conntrack_{standalone,core,netlink}.c and ip_nat_{core,standalone}.c and logging of invalid packets ("echo 255 > /proc/sys/net/ipv4/netfilter/ip_conntrack_log_invalid"). I hope this will give some clues .. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
