FTP on 951Ui-2HnD

Hi, how to enable FTP 951Ui-2HnD with connected usb flash memory access from wan. From LAN it is working.

Wan FTP access too, printscreen for your Firewall filter rules (or export compact firewall rules)

  1. Enable ftp from ip>sevices.
  2. Your external ip
  3. Set a new user for ftp, with proper ftp rights.

Default firewall rules in most RouterBOARDs include a filter for any incoming connections from WAN.

To allow FTP from all interfaces, while still prohibiting everything else from WAN, run the following command from terminal:

/ip firewall filter add place-before=[:pick [find chain=input] 0] chain=input action=accept protocol=tcp dst-port=[/ip service get ftp port]

WHAT IS THE FINAL OF THIS ISSUE?

Could you elaborate on above?
