[Xen-users] Martian Source Networking Errors

[Bill Denney <denney@xxxxxxxxxxxxxx>]

Hello,

I've been having trouble with networking a win2003 domU in a SLES 10 
dom0.  dmesg is reporting messages like
Jan 18 02:40:59 xen0 kernel: martian source 169.254.244.56 from 
169.254.244.56, on dev tun0
Jan 18 02:40:59 xen0 kernel: ll header: 
ff:ff:ff:ff:ff:ff:00:16:3e:04:63:ba:08:06
when I try to allow the domU to get its own ip address via DHCP, and it 
gets messages like
Jan 18 02:48:50 xen0 kernel: martian source 192.168.200.255 from 
192.168.200.135, on dev tun0
Jan 18 02:48:50 xen0 kernel: ll header: 
ff:ff:ff:ff:ff:ff:00:16:3e:04:63:ba:08:00
when I try manually setting the ip address.

With these errors I'm obviously getting no networking.  I've tried both 
enabling and disabling SuSEfirewall2 to no effect.  Any suggestions on 
how to make the kernel not drop these packets but forward them on 
through the bridge correctly?
Thanks,

Bill
