Problem with Beta 5.0:
the new blacklist contains some entries from the former whitelist.
Are you sure it happened during during the beta upgrade process? There are also some issues associated with teleporter in your debug log. I'd say it's more likely that something went wrong during an import, what you you think? Would that be possible?
I noticed and fixed the wrong import immediately after the migration.
For other reasons I had to do a rollback of the system via timeshift yesterday, which produced the configuration artifacts. The setup was done in the 192.158.2.0/24 range before my gateway went live.
On this occasion, I noticed the bug with the import again and I decided to report it to some extent afterwards.
This issue is that (a) noone else reported this (okay, you may just be the first one, so that's not ruling it out) but (b) that I closely followed the code now and don't see how they can land in the wrong table. Maybe it is just a displaying issue, can you check on the new "Group Management -> Domains" page if they are off there as well?
