Re: What do you want your ISP to block today?

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. 

One basic issue is that people discussing this topic on 
mailing lists like these are not average home users. Most
of us here have seen a DOS prompt at some point and know
about "Service Packs" and "Hotfixes".
