Hi all I am getting the following martian kernel messages since I changed my ISP: martian source 81.56.221.174 from 127.0.0.1, on dev ppp0 ll header: 45:08:00:28:da:b8:00:00:7d:06:b5:27:7f:00:00:01:51:38:dd:ae:00:50 Now here is the configuration of my box: I have an ADSL/Ethernet modem on ppp0: ppp0 Link encap:Point-to-Point Protocol inet addr:81.56.221.174 P-t-P:192.168.254.254 Mask:255.255.255.255 The modem is connected to eth0: eth0 Link encap:Ethernet HWaddr 00:60:97:4B:82:AA inet addr:10.0.0.1 Bcast:10.0.0.255 Mask:255.255.255.0 Additionally I have the loopback interface(127.0.0.1) and one more interface for local network: eth1 Link encap:Ethernet HWaddr 00:60:97:75:B4:28 inet addr:192.168.0.254 Bcast:192.168.0.255 Mask:255.255.255.0 I am running SuSEfirewall2 as FW and NAT router. Here are the main config parameters: FW_DEV_EXT="ppp0 eth0" FW_DEV_INT="lo eth1" FW_ROUTE="yes" FW_MASQUERADE="yes" FW_MASQ_DEV="ppp0" I don't see where I am getting these "martian packets" from. I need some help. Cheers Pep Serrano.
