TEREDO TEREDO: Tunneling IPv6 over UDP through NATs ?

Tunneling IPv6 over UDP through NATs

Hi,

Im using MS port monitor to keep an eye on socket packets.

Not sure what the above is. Can anyone help ?

(where 99.99.99.99 is my masked destination IP)
(where 8888:84F0:5586:8888:88:8888:8888:8888 is my masked source IP in IPv6
format i guess).

Thanks for any help
Scott

 

We propose here a service that enables nodes located behind one or
more IPv4 Network Address Translations (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. The relays can also provide interoperability
with hosts using other transition mechanisms such as "6to4".
