The Config Backup Server Everyone Can Reach

Restrict a file transfer service to the segment that is supposed to use it.

Escenario

The configuration backup server holds a copy of every device config on the network, and it is currently reachable from the user LAN as well as from the management subnet. Nothing has been taken, and the protocol offers no authentication worth depending on. Restrict access to the management subnet, leaving the administrators' own backups working.
