Description Christian Völker univentionstaff 2019-09-12 11:00:55 CEST
Customer tried to configure UCS to use IPv6 addresses.

He got a "/64" network. 

UMC requests to enter the "IPv6 Adresse", "IPv6-Präfix" and "Bezeichner".

According to the documentation you must set the "Bezeichner" for the first IPv6 address to "default". Trying with different values here failed when saving.

So this is absolutely NOT intuitive. Yes, customer should read documentation. But just for entering a network address?

At least add a help text or set the desired value by default. Or just remove "Bezeichner".

when entering the prefix as prefix (ie 2a00:4f80:71:1) instead of the netmask (/64) it will simply not save the settings.

Again, match description or accept values.

Getting frequent complains meanwhile about this. See ie forum (this on from last year but getting more and more)

I guess it is some sort of low-hanging-fruit to fix the UMC masks and syntax.
