The Host Identity Protocol (HIP) fundamentally changes the way in
which two Internet hosts communicate. One key advantage over other
schemes is that HIP does not require modifications to the traditional
network-layer functionality of the Internet, i.e., its routers. In
the current Internet, however, many devices other than routers modify
the traditional network-layer behavior of the Internet. These
"middleboxes" are intermediary devices that perform functions other
than the standard functions of an IP router on the datagram path
between source and destination hosts. Whereas some types of
middleboxes may not interfere with HIP at all, others can affect some
aspects of HIP communication and others can render HIP communication
impossible. This document discusses the problems associated with HIP
communication across network paths that include specific types of
middleboxes, namely, network address translators and firewalls. It
identifies and discusses issues in the current HIP specifications
that affect communication across these types of middleboxes.

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.
