I'm trying to connect to an FTP server that is behind a NAT. The local IP of the server is 172.23.11.41 and the public IP is 22.214.171.124, and I'm connecting to the public IP.
When entering passive mode the server returns its local IP address which is useless. Example:
227 Entering passive mode (172,23,11,41,234,113).
The Linux command-line ftp client cannot establish a data channel when this happens.
I need to get the ftp client to ignore the IP address returned by passive mode (PASV) or to use extended passive mode instead (EPSV), which only returns the port number. Example:
229 Entering extended passive mode (|||64607|).
Is there any way to do this?
I'm being told that we use ftp.x86_64, installed by calling
sudo yum install ftp.
