OK Alberto, it's more clear now.
I'm going to give you a help in your stunnel integration with zen. If you
have problems with the sync of directories you can change easily the params
that rsync uses for do it, in the web gui go to "Setting >> Server" and
take a look in the field named *Rsync replication parameters, *those values
are used by rsync command line for syncing config directory content
