Hi,
 
so far my settings works but a major problem is
that all the traffic during a "Server to Server" session goes
through my Masquerading Router (SourceServer->MyMasqRouter->DestServer).
I read the manuals and tested all possible setting so far, but I can't solve this problem.
 
In addition I include my ftp-proxy.conf:
