[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.
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.
-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:
+Under Windows you can use the Teredo client that comes with Windows XP SP2 and above, or prior versions with the [Advanced Networking Pack|http://www.microsoft.com/downloads/details.aspx?FamilyId=E88CC382-8CE6-4739-97C0-1A52A6F005E4&displaylang=en]
. To enable this you need to run at the cmd prompt:
<pre>
ipv6 setup
netsh interface ipv6 set teredo client
</pre>
+Windows can tell you whats going on by:
+<pre>
+ netsh interface ipv6 show teredo
+</pre>
now you should be able to use [VoIP] and [P2P] applications that support [IPv6] as if you had a real world IP address.
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
!)
+* You have a "symmetric
[NAT]" (check the list at the bottom
of this page
, and
please update
it!) the only solution here is to find some other way to get an IPv6 address (maybe 6to4 on your NAT device) or replace your NAT device. Sorry.
+** Linux 2.4 and above use symmetric NAT, if this is your problem, try setting up [6to4] on your Linux box instead of using Teredo.
* Theres a firewall between you and the teredo server.
-* You're on a domain
+* You're on a Windows
domain (in that case use =netsh interface ipv6 set teredo enterpriseclient= instead)
+
+Various types of [NAT]s that do and don't work:
+* Symmetric [NAT] (Doesn't work with teredo):
+** Linux
+
+* Cone [NAT]
+** monowall (FreeBSD kernel)
