thank you lleachii,

it turned out... i am not stupid at all.
one my AVM 4040 OpenWRP does not resolve ddnss.de.
tried hard 2 weeks and ended at changing my 4040 (got 4 in total).
other box resolves ddnss.de and my goal S2S AVM 7530 7.39 <-> AVM 4040 OpenWRT works

still dont know why this happens. will try to recover to 7.14 old on 4040 and reflash OpenWRT again.

greetings michael
