No. ISPs should not block ports unless they are listed in the AUP as non-permitted traffic or it is a necessary and temporary remedial action for a service-affecting problem.
I fully agree that ISPs should include the list of blocked ports in their AUP. (somewhere in the paper it mentions the confusion caused by uncoordinated filters).
I still do not understand why a manufacturer is permitted to release a product which causes such harm, and, rather than hold that manufacturer liable, so many people feel that the entire rest of the world should change to accommodate that one manufacturer's deficiencies
But should the end user pay for the faults? They already pay for the software and the Internet connection. How many ISPs on this list provide support for non-MSFT operating systems? Does the free CD you hand out run on anything but Windows? 90% + of internet users do use MSFT Windows. So I don't think you have a choice other than to "live with it". -- -------------------------------------------------------------- Johannes Ullrich jullrich@euclidian.com pgp key: http://johannes.homepc.org/PGPKEYS -------------------------------------------------------------- "We regret to inform you that we do not enable any of the security functions within the routers that we install." support@covad.net --------------------------------------------------------------
