In linux kernel since version 2.6.12
FTP is a protocol that transfers IP address and/or port number in
the payload. In the virtual server via Network Address Translation,
the IP address and port number of real servers cannot be sent to
clients in ftp connections directly, so FTP protocol helper is
required for tracking the connection and mangling it back to that of
virtual service.
If you want to compile it in kernel, say Y. To compile it as a
module, choose M here. If unsure, say N.
