FTP, or File Transfer Protocol, used extensively for basic file upload and downloads. If you will be making FTP service available to this device outside the firewall, you can specify a custom port for added security. 
Port: 21   
Authentication mode: User 
Allow upload resumes: Enabled   
Passive ports: 1024 − 65535
Masquerade as: nas-xx-xx-xx
Thanks in Advance.
