My previuos seemd to get a few views but no help. Surely someone has an FTP server behind an Astaro firewall so I could use your recommendations.
I had setup the FTP connection using FTP Service provided and this worked but then I got 3000+ failed login attempts on the Windows Server I'm trying to protect. I only need this access form a small group and decided to change the system to use port 2100. I created a new service FTP-SECURE with a destination port 2100, did the NAT and PF changes, and also set up Windows FTP for 2100.
From inside the firewall I can FTP to the Windows system on port 2100 and all works fine. From outside the firewall I can FTP to port 2100 and connect and login BUT if I try to run the dir command (or several others) it fails with an error;
500 "EPSV" command not understood
Any comment or suggestions?
