Here is a ruleset which grants access to the FTP proxy based on client IP. Only IPs in the list "Allowed FTP Subnets" are allowed to use the FTP Proxy. All others are blocked. The ruleset criteria is "Connection.Protocol equals FTP".
See attached ruleset. Let me know if I misunderstood the request.
