Hi, just yesterday a larger german DSL/Internet provider activated - without a real notice - a feature as "field trial" in my city, so that HTTP(S) requests of customers are redirected to their own web portal (apparently using some soft state timeout). I'm also aware of several other dial-up providers who do that. This breaks IMHO a lot of applications, e.g., DynDNS registrations of DSL routers (which would not be necessary with IPv6 but that is another issue), automated Windows/Linux updates, anti-virus database updates, RSS and presumably many more. Though they sell it as a "service to customers" (luckily you still can turn this feature off if you know how to do it...), I see it as very dangerous since automated security updates etc. will fail, i.e. they even decrease the security of their cutomers! Is there anything newer than RFC 2775 that one could give as strong technical advice to abandon that feature and to not turn it on for all other users? Regards, Roland P.S.: please don't comment that I should just switch the provider in this case. I like to raise the awareness of the provider that this feature is _technically_ dangerous, though it may make a lot of sense for the marketing people... _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
