Problem With Android Configuration

I think it's more of a routing issue than anything explicitly blocking it,
they use a new 'ip rule list' and per user settings that aren't well
documented yet either, but where exactly to point I don't know. I haven't
messed with android 5 much yet, it seems not ready enough yet for daily
use, there isn't a single snapshot in the cyanogenmod repos, for example.
So maybe it's worth to just stick with Android 4 for now?
Met vriendelijke groet / Kind regards,
Alexander Ypema
