Thanks for the feedback Erich! In the mean time, the Bluewin hot-line called back (yes, I know, I couldn't believe it either :-)) but they had no special information: they just confirmed nothing happened this night about the setup. Asking on #swinog (irc) helped a bit more: it seems some other people had the same problem, and as a solution the suggestion was: "if you do NAT on Zyxel router please consider to close port 80 or block the IP 212.224.127.14" (thx Claudio). I did that on the routers (by luck a good old isdn-based dial-in was available everywhere), and now everything looks stable.
