Yes, this is how it should work.

Yes.

With myracloud CF-Connecting-IP and remote_addr are set to client ip and
real remote is myracloud ip. botlimit is set to remote_addr in general and
to x.x.x.x if hits in geo given ip address. So far as I expected and now it
works. I don't know why, but I have a better understanding because of your
help, thanks!

A trifle still ... is set 

limit_req_status 429;
limit_conn_status 429;

But in access.log I get 503, why?
