This draft is a work item of the IP Security Protocol Working Group of the IETF.
Title : UDP Encapsulation of IPsec Packets
Author(s) : A. Huttunen et al.
Filename : draft-ietf-ipsec-udp-encaps-00.txt
Date : 21-Jun-01
This draft defines methods to encapsulate and decapsulate ESP and
AH packets inside UDP packets for the purpose of traversing NATs.
ESP encapsulation as defined in this document is capable of being
used in both IPv4 and IPv6 scenarios. AH encapsulation is defined
for IPv4 scenarios only.
The encapsulation is used whenever negotiated using IKE, as
defined in [Kiv00]. The design choices are documented in [Dixon00].

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
