The default source IP address for the FTP server to send packets is 0.0.0.0.
Format

undo ftp server source
Parameters
| Parameter | Description | Value |

- |
| -i interface-type interface-number | Specifies the loopback interface of the FTP server as the source interface.

Usage Guidelines
Usage Scenario
If no source IP address (0.0.0.0 by default) is specified, the FTP server uses the source IP address specified by routes to send packets. The source IP address must be configured for an interface with stable performance, such as the loopback interface. Using the loopback interface as the source IP address simplifies the ACL rule and security policy configuration. This shields the IP address differences and interface status impact, filters incoming and outgoing packets, and implements security authentication.
Precautions
- After the source IP address is specified for the FTP server, you must use the specified IP address to log in to the FTP server.
- After running the ftp server-source command, you can only use the specified IP address or loopback interface of the FTP server for login. You need to restart the FTP service to activate the configuration.
- If the ftp server-source command is not configured, all users can log in to the FTP server by default.
- If the FTP service has been enabled, the FTP service restarts after the ftp server source command is executed.
Example
# Set the source IP address of the FTP server to LoopBack0.
