Userland ftp-proxy application significance

  • i just want to ask you guys about the significance of disabling the userland ftp-proxy application in the LAN and DMZ interface, what would happen if i disable it? if i enable it?


  • It changes the IPs inside the ftp protocol to make it work with NAT and punches dynamically ports open that are needed for the ftp transfer. ftp doesn't happen on one port only (TCP 21 is only the controllsession).
