cPanel & WHM's implementation of PureFTP and ProFTPd causes an issue on NAT-configured networks. This issue prevents Passive FTP connections to other IP addresses on the server, and connections via domains that resolve to other IP addresses.
The following workaround is a temporary fix. The next time you reconfigure the FTP server, the system will automatically re-add the
MasqueradeAddress settings to the configuration file.
In order to work around this limitation, perform the following steps:
1. Follow the existing procedure in the How to Enable FTP Passive Mode document to configure Passive FTP on a NAT-configured network.
2. Remove the
ForcePassiveIP setting from the
/etc/pure-ftpd.conf file or the
MasqueradeAddress settings from the
3. Restart your FTP server.
You should be able to connect to all FTP-enabled domains on the server via a Passive FTP session.
Because NAT configurations are commonly associated with secure environments, we strongly recommend that you use our Web Disk feature instead of FTP for file transfers. Unlike FTP, Web Disk encrypts usernames and passwords, and it transfers files over secure connections.
