External requests are distributed by port or using sniproxy (in particular 443), and all externally visible names are in a distinct zone then my domain, but with an additional indirection: names like backup.lindenberg.one resolve to CNAME backup.rot.lindenberg.one, and only backup.rot.lindenberg.one is resolved differently internally/externally.
No, you want to implement split horizon/split brain, but you shouldn't, 
you should have used a subdomain of your external domain for the AD dns 

As far as I am aware, you need Windows 2016 to have any chance of 
something like this working.
