RE: Question about Martians on Vyatta

[Eric Germann <egermann () limanews com>]

Well, I did when I checked them shortly after I saw the log messages.

Wondering now if the routes for those bounced and in the "middle" of the bounce, they're considered martian.

Thanks!

Do you have routing-table entries which cover those IPs?  Try "ip route show <ip>" as root.

Linux NET/4 stack considers (as far as IPv4/IPv6 go) anything that is not in the routing table or an immediate 
neighbour as "martian."
