Title : Teredo: Tunneling IPv6 over UDP through NATs
Author(s) : C. Huitema
Filename : draft-ietf-ngtrans-shipworm-05.txt
Pages : 49
Date : 20-Feb-02
We propose here a service that enables nodes located behind one or
several IPv4 NATs to obtain IPv6 connectivity by tunneling packets
over UDP; we call this the Teredo service. Running the service
requires the help of 'Teredo servers' and 'Teredo relays'; the
Teredo servers are stateless, and only have to manage a small
fraction of the traffic between Teredo clients; the Teredo relays
act as IPv6 routers between the Teredo service and the 'native' IPv6
Internet. A set of Teredo clients, servers and relays constitute a
Teredo Network; this document specifies both a global Teredo
network, which does not require configuration by the clients, and
the possibility to organize local Teredo networks, e.g. within a
specific domain or region. A Teredo network is characterized by an
IPv6 address prefix and by a unique IPv4 address used by all servers
and relays in the network.

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.
