FTP active data connection port
Hi, I have a problem where I try to connect to my server with an FTP client and the connection at some point tries to connect to a random data port > 50000.
Obviously a firewall blocks that connection. Changing my data center firewall settings is something too arduous to think about, except maybe as a last resort. I though that FTP would use port 21 or 22 normally. I'm using pure-ftp as the ftp server. I have passive mode disabled and using active mode on the client too (which is FileZilla). Why is the client trying to connect to a port like that and can I somehow change the port(s) used?

Nevermind... I figured it out. The connection is from server to client, so the problem is on the client side. 0 -
