Hi Julien, thats exactly the setup I'm actually using. I use my relay as a client.
>From my point of view it seems that the relay is used as a entry point
(without guard flag) in this constellation (correct me if I'm wrong).
Torsocks could solve my problem.
My goal is to examine the influence of a high traffic load on my relay
to perhaps adjust my server settings (number of open file descriptors,
...).
