Specifying the source interface and source IP address for an FTP server
You can specify the source interface and source IP address for an FTP server to enhance server
security. After this configuration, FTP clients can access this server only through the IP address of the
specified interface or the specified IP address.
Source interface refers to the existing VLAN interface or Loopback interface on the device. Source IP
address refers to the IP address configured for the interface on the device. Each source interface
corresponds to a source IP address. Therefore, specifying a source interface for the FTP server is the
same as specifying the IP address of this interface as the source IP address.
Follow these steps to specify the source interface and source IP address for an FTP server:
