Description ume 1999-10-13 17:50:01 UTC 
	In RFC2428 (FTP Extensions for IPv6 and NATs), new FTP command
	EPRT was defined.  The EPRT has IP address in a command, like as
	PORT command.  So, to use EPRT, NAT box should know what EPRT is.
	Though EPRT is defined in conjunction with IPv6, EPRT itself is
	protocol independent, and usable with IPv4.
	In IPv6 enabled distribution such as NetBSD-current, FTP client
	try EPRT first, and if fail, fall back to use PORT as default.
	In this senario, if FTP server speak EPRT, FTP data connection
	would be blocked by NAT box.

Fix: 

Please apply the patch resides in:

How-To-Repeat: 
	Ftp to the server which support EPRT, using EPRT supported
	FTP client.
