I'm getting the occasional Feb 1 13:17:08 yendi kernel: NAT: 0 dropping untracked packet c3ea4da0 1 146.188.249.73 -> 209.220.232.240 syslog message. What exactly does it mean? 146.188.249.73 isn't my machine at all, and 209.220.232.240 is my firewall. I assume I'm dropping someone's packets on the floor, but what can cause a packet to get dropped like that? -- Dave Meyer dmeyer@dmeyer.net - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
