Squid configuration directive ftp_epsv

Available in: 3.3   3.2   3.1   3.HEAD  

History:

Changes in 3.1 ftp_epsv

New directive to control whether Squid uses EPSV extension for efficient NAT handling and IPv6 protocol support in FTP.

Configuration Details:

Option Name:ftp_epsv
Replaces:
Requires:
Default Value:ftp_epsv on
Suggested Config: 


	FTP Protocol extensions permit the use of a special "EPSV" command.

	NATs may be able to put the connection on a "fast path" through the
	translator using EPSV, as the EPRT command will never be used
	and therefore, translation of the data portion of the segments 
	will never be needed.

	Turning this OFF will prevent EPSV being attempted.
	WARNING: Doing so will convert Squid back to the old behavior with all
	the related problems with external NAT devices/layers.

	Requires ftp_passive to be ON (default) for any effect.
