I am having this problem since I set up the firewall; my syslog file is full with these messages:


fw kernel: martian source 201.225.XXX.XXX from 201.225.XXX.XXX, on dev eth1

fw kernel: ll header: ff:ff:ff:ff:ff:ff:00:a0:c5:69:0f:7c:08:00

fw kernel: martian source from, on dev eth0

fw kernel: ll header: ff:ff:ff:ff:ff:ff:00:07:95:2e:5e:66:08:00


This is my config:


Mandrake with Shorewall over iptables, and NAT on the eth1 lan device.


Eth0 to the Internet connected to a hub, where the Internet router is connected.

Eth1 to the lan connected to a different hub (both hubs are interconnected)


I know the problem is because the fw nat is sending packages from one device to another, but I don’t know how to fix the martian sources issue.


Thanks in advanced.
