Well, I see that I don't really manage to state the situation short, complete and without ambiguities XD

I get direct connection mode only when physically connected to LAN /WLAN with any device OR under android (mobilphone) when connected via UMTS

(android -> hotspot -> Laptop)
I get mydownloader server mode when I try to share the UMTS signal from the android device to my laptop
Also server mode when using VPN connection from laptop



Android -> VPN -> NAS is an option i did not try yet ^^. But that's another VPN(NAS-hosted) connection, not the one mentioned before (foreign LAN-hosted)
This brings direct connection mode as well.

Maybe it just doesn't work and the android app keeps lying?^^ -> no, since browser based works too, in physical LAN
