RB1100.

Trying to route public and VPN FTP requests on port 6926 through Mikrotik and to internal LAN FTP on port 21. I can connect to FTP, log in, but not list/transfer directories/data. What am I missing?

Configure NAT rule for FTP data (check FTP server 'passive ports' settings), not only for FTP command (port 21).

HTH,

HTH,

It does, but in the process of investigating this, it occurred to me that we were trying to make a 1950's engine work in a 2010 vehicle. I've scrapped this whole FTP thing do to the inherent security risks involved. Thanks for the reply!
