If I'm not mistaken, the 00:01:03 block belongs to 3Com. Check to see if
you've got any machines with 3Com NICs. Check your DSL modem - it may be
trying to provide NAT services itself. Otherwise, see if the MAC listed
is that of your ex0, and make sure the two LANs are physically
seperated. I don't THINK netbsd will forward ethernet frames across
interfaces, unless the bridge device is configured and enabled, but...
perhaps something has changed...
