RE: NetBIOS Messenger spam - how did it get in?

1. Is this possible? I would have thought any packet
with such a spoofed IP address would be deemed
non-routable by any of the routers between the source
host and mine, and hence would never make it to my host?
The destination (your external address) is routable. Source is ignored
unless prohibited. Non-routable addresses are not allowed to be the
destination on the public Internet.
