-[Teredo|http://www.microsoft.com/technet/prodtechnol/winxppro/maintain/teredo.mspx] is a method of tunneling [IPv6] packets over [IPv4] in such a way that allows the packets to travel through
[NAT]. This can be used by peer to peer applications to allow two people behind seperate NAT's to talk to each other directly thus making the peer to peer
networks more efficient
.
+[Teredo | http://www.microsoft.com/technet/prodtechnol/winxppro/maintain/teredo.mspx] is a method of tunneling [IPv6] packets over [IPv4] that is capable of providing direct connections even
in situations where both ends are behind
[NAT] gateways
. The efficiency of virtual PeerToPeer
networks greatly benefits from this capability
.
-Under Linux/FreeBSD
you need to
have [IPv6] in your kernel
, and need
to install/run http://www.simphalempin.com/dev/miredo/
in client mode
.
+However, it does require that
+* there is no FireWall between
you and the [Teredo] server
+* you don't
have a realworld
[IPv6] address from somewhere else
+* you are not behind a ''symmetric [NAT]'' or ''cone [NAT]'' gateway. If so
, you may be able
to employ some other means such as setting up [6to4] on the [NAT] device
in order to get an [IPv6] address
.
-Under Windows you can use the Teredo client that comes with Windows XP SP2 and above. To enable this you need to run at the cmd prompt:
-<pre>
- ipv6 setup
- netsh interface ipv6 set teredo client
-</pre>
+!!! Implementation notes
-now you should be able to use
[VoIP
] and
[P2P
] applications that support [IPv6] as if you had a real world IP address.
+[Linux
],
[FreeBSD
]::
-Teredo won't work if:
-*
You have a realworld
[IPv6] address from somewhere else
.
-* You have a "restrictive
[NAT]" (
if you have one of these
, please list it here!)
-* Theres
a firewall between you and the teredo server
.
-*
You're
on a domain
+
You can use [Miredo | http://www.simphalempin.com/dev/miredo/]'s client mode to implement [Teredo] on [Linux] or [FreeBSD], provided your [Kernel] has
[IPv6] support
.
+
+ Notes:
+
* [Linux] 2.4 and above use symmetric
[NAT] --
if this causes problems
, set up [6to4] on your [Linux] box instead.
+
* It won't work on [m0n0wall], which uses cone [NAT] on
a [FreeBSD] [Kernel]
.
+
+ <br>
+
+MicrosoftWindows::
+
+ <br>
You need XP Service Pack 2 or the [Advanced Networking Pack | http://www.microsoft.com/downloads/details.aspx?FamilyId=E88CC382-8CE6-4739-97C0-1A52A6F005E4&displaylang=en]. On a CommandLine, do:
+
+ <pre>
+ ipv6 setup
+ netsh interface ipv6 set teredo client
+ </pre>
+
+ Note: if you are
on a MicrosoftWindows
domain you must substitute <tt>client</tt> for <tt>enterpriseclient</tt>.
+
+ Now you should be able to use [VoIP] and [P2P] applications that support [IPv6] as if you had a realworld [IP] address.
+
+ You can monitor the interface using:
+
+ <pre>
+ netsh interface ipv6 show teredo
+ </pre>
