Quite easy [snip] What does "kernel: martian source aabbccdd for 11223344, dev eth0" mean? These are packets that Linux does not expect from the direction they came from (i.e. packets from internal hosts coming in on the external interface). The cause is probably a misconfigured machine on your LAN. You can turn off logging those packets via /proc/sys/net/ipv4/conf/*interface*/log_martians which is documented in /usr/src/linux/Documentation/proc.txt [snap] Michael Appeldorn
