	Title		: Transient pseudo-NAT attacks or how NATs are even more
                          evil than you believed

When a 'NAT traversal' capability is added to a class of signaling
protocols which can control some traffic aggregation points,
a new attack based on a temporary access to the path followed
by messages.
Mobile IP [1] with NAT traversal [5] or IKE [2] with NAT
traversal [6], including the IKEv2 [7] proposal, are potential
victims of this kind of attacks.
This document claims the vulnerability is an intrinsic property
of the NAT traversal capability, so is a new point where the
usage of NATs is very damaging.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	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
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
