Basically my network was unable to connect to the Internet. My Linux box masq'ing for the network had the messages listed below on the screen. I tried bringing up and down all the eth cards to get their ip's again but that was a no go. Only a reboot solved this. I understand that they are called Martians because they are invalid internet ip's. What I would like to know is if they are somthing coming from my cable provider's network (like their DNS or DHCP servers) or from someone in my neighborhood not exactly sure of what they are doing.
BTW - It is not me (I hope) because I use Class C (192.168.XXX.XXX - these are class c right?) private addresses for my internal network.
Here is are some of the logs:

PS - 24.48.XX.X is the ip address of my ip's name servers. Thats is why I thought the trouble might be coming from their network.... And eth1 is my external interface.

PSS - the title was supposed to say Martian instead or Martion. I must have typpped toooo fast and not have speel chequeed it.
