Re: rfc 1918?

There are good reasons to want to get those packets (traceroutes from
people who have numbered their networks in rfc1918 networks, f'rinstance).

The original note specifically showed them as being TCP packets from
a 10.x.x.x address going to port 80.  Does that qualify as a good reason?

Err, no, but I don't think it's reasonable to expect people to filter rfc1918
packets based on specific protocols.

Not everyone agrees whether it is better to filter or not to filter,
but there are good arguments on both sides.

Does anybody in the house think that these packets actually have a snowball's
chance in Hades of getting a reply back sucessfully?

No, but that's really a thoroughly orthogonal question.
