If you review the NANOG archives you'll find that at least in the case of the port 25 absurdity, I have noticed and have railed against it.Yeah, I threw it in as an afterthought. ISP firewalls do exist and not just small isolated incidents. I wish more money had gone into making them much more adaptive, then you could enjoy your tcp/25 and possibly not have a problem unless your traffic patterns drew concerns and caused an adaptive filter to block it (eh? thousands of emails suddenly to a variety of servers? block). Interestingly, adaptive filters are often used for probing scans (and we didn't apply them to tcp/25, why?) Jack
Sad, but true. I will not patronize an ISP that decides for me which packets I want and do not want, but, apparently there are people who will. Not sure how I feel about a more adaptive version. Sounds like it would be better than the current state, but, I vastly prefer "I pay, you route. If I want filtration, I'll tell you." Owen
