FTP Passive Mode

Issue:

Implementing proftpd with TLS/SSL in zPanel with access issue through firewall.

Solution:

Besides port 21 for standard ftp and ftp with explicit SSL/TLS, need to forward range of port for Passive Mode.

Configuration:

  • Centos  6.4
  • zpanel  10.1.0
  • proftpd 1.3.3g

Tricks:

Both the server firewall and the router port forwarding should be configured.
