I must be very tired... I replied to the wrong address (thanks Pascal). I am forwarding them to the right place now. --- *B. R.*

I didn't even make the effort to think over the /128. And also about the network mask... I feel stupid about that now :oP No, I don't have much more details from my hoster. My contact is relaying information from their "network team", he doesn't seem to understand much more than me what he is talking about... I don't know what to seek for with tcpdump, honestly. The router I was talking about seems to be the device their log trace wastaken from. I do not handle routing of anything on the network, I just own a server over there. I'll try to get information from their side. --- *B.
