I asked this question on Whatsup and there was no help, I hope someone here can clue me in, given that I'm not exactly an expert network manager...
I've switched from ADSL to cable yesterday, and although the network seems to work, I constantly get martian messages in the kernel log, which probably means that something is misconfigured. I want to know if it's my setup, something at the cable company, something at actcom, and whether it's solvable. My network contains two computers. The Linux is connected through eth1 to the Internet via cable modem and a dialer to actcom. Its eth0 is connected to the local network, that is to the switch to which the other machine is also connected. The addresses on that subnet are 192.168.1.*. Firewall and masquerading are done by shorewall running on the Linux (which is a Mandrake 10 OE). eth1 is configured with DHCP. eth0 is configured statically. Here is a sample of the martian messages: Oct 18 20:12:01 Motti kernel: martian source 172.27.107.135 from 172.27.96.1, on dev eth1 Oct 18 20:12:01 Motti kernel: ll header: ff:ff:ff:ff:ff:ff:00:0f:34:7b:c8:a0:08:06 Oct 18 20:12:06 Motti kernel: printk: 217 messages suppressed.
