        Title           : IAB Considerations for UNilateral Self-Address Fixing 
                         (UNSAF)
        Author(s)       : L. Daigle
        Filename        : draft-iab-unsaf-considerations-01.txt

With current NA[P]T middleboxes, individual networks using different
address realms are bridged.  However, as a side effect of address
translation, communicating endpoints on either side of the middlebox
do not know how to refer to themselves using addresses that are
applicable in the other realm -- the address translation is locked
within the middlebox.  Various proposals have been made for
'UNilateral Self-Address Fixing (UNSAF)' processes.

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
Internet-Draft.
