IPsec architecture is based on the concept of keeping data secure
while it is being transported across a network. Therefore there are
problems when packet headers change while in transmit across the
network, by virtue of NAT devices.
This draft details the changes needed in order to make both initial
IKE negotiation and subsequent authenticated/encrypted
communications across IPsec AH/ESP SAs work despite the changes in
the headers, and possible protocol transformations.

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.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
