Perhaps the most common use of IPsec is in providing virtual private
networking capabilities. One very popular use of VPNs is to provide
tele-commuter access to the corporate Intranet.  Today NATs are widely
deployed in home gateways, as well as in other locations likely to be
used by tele-commuters, such as hotels. The result is that IPsec-NAT
incompatibilities have become a major barrier to deployment of IPsec in
one of its principal uses. This draft describes known incompatibilities
between NAT and IPsec, and describes the requirements for addressing
them.

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.

implementation to automatically retrieve the ASCII version of the
