[IDEA] Security - which user really need to login

[UpsiUps]

I am not sure how the situation is in US or GB, but in Germany the suggestion is to use IP6 overall. At the moment a dual stack is often used, but in some cities you only get a IP6 stack.

I agree with you, that the missing NAT and the exposure of all devices is a nightmare - and one of the reasons, why IP6 is not used very often in a dual stack environment.
