I just read the paper... Sounds like as an ISP, I should offer a new product "The Internet Minus Four Port Numbers Microsoft Can't Handle." What I can't tell is whether this should cost more or less than "The Internet" Matthew Kaufman
On Behalf Of Johannes Ullrich:
I just summarized my thoughts on this topic here: http://www.sans.org/rr/special/isp_blocking.php>
Overall: I think there are some ports (135, 137, 139, 445), a consumer ISP should block as close to the customer as they can.
