Why do you think this packet is generated locally? 123.23.23.23 is the address of the machine's eth1 (Internet) interface. Since this only happens when I boot into certain kernel versions (2.6.20 and 2.6.21), it seems unlikely that someone on the Internet is sending me ICMP packets with a spoofed source address. -- Jordan Russell
