	Title		: Inappropriate TCP Resets Considered Harmful
	Author(s)	: S. Floyd
	Filename	: draft-floyd-tcp-reset-00.txt
	Pages		: 10
	Date		: 07-May-01
This document is being written because there are a number of
firewalls in the Internet that inappropriately reset a TCP connection
upon receiving certain TCP SYN packets, in particular, packets with
flags set in the Reserved field of the TCP header.  In this document
we argue that this practice is not conformant with TCP standards.  We
further argue that this is a harmful practice that, by blocking off
things new or unknown, presents a significant obstacle to the
evolution of the Internet infrastructure.

NOTE:	The mail server at ietf.org can return the document in

	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with

	how to manipulate these messages.
