IMO, Commercial ISPs should never filter customer packets unless specifically requested to do so by the customer, or in response to a security/abuse incident. Consumer ISPs are much more likely to have clauses in the AUPs that are enforced premptively via packet filtering - antispoof filters (honestly, antispoof filtering is, IMHO, the one expection to my "commercial ISPs should not filter" rule), port blocks to prevent customers running servers, outbound SMTP blocks to off-provider systems to stop direct-to-MX spamming, ICMP rate limiting, et al. All of which are fine by me as long as they clearly assert their right to do so in their AUP - that is, as long as there's a comparable provider I can use instead. -C On Sun, Aug 04, 2002 at 02:37:12PM +0000, bmanning@karoshi.com wrote:
Good day,
What NSPs do filter packets, and can really deal with DoS and DDoS attacks?

The shorter shorter list would be the NSPs that do NOT filter packets. I can't think of an NSP that does not filter.
