Title: World IPv6 Day and how to connect FreeBSD through a Teredo Tunnel

---------------------------------------------------


It has finally arrived, the World IPv6 Day!

So you don't have native IPv6 network access? No problem, just use a Teredo Tunnel to get connected.
Here's a very short primer on doing so on FreeBSD.


Firstly install the miredo package from the ports tree.


[root@GPWS ~]# cd /usr/ports/net/miredo/
[root@GPWS /usr/ports/net/miredo]# make clean install


Alternatively, install the binary package:


[root@GPWS ~]# pkg_add -r miredo


Enable miredo in your rc.conf:


[root@GPWS ~]# echo miredo_enable=YES >> /etc/rc.conf


Make sure to have a proper /usr/local/etc/miredo.conf.
Here's my very minimalistic config:


#! /usr/local/sbin/miredo -f -c
#
RelayType client
InterfaceName   teredo
#BindPort            3545
#BindAddress     192.168.2.1
ServerAddress teredo.ipv6.microsoft.com


Note: Depending on your setup, e.g. with multiple interfaces, you may need to specify a BindAddress to use the proper network interface.
So to speak, you may need to specify also a specific port for some NAT setups.

Now fire up miredo:


[root@GPWS ~]# /usr/local/etc/rc.d/miredo start


You should end up with a new network interface by the name of 'teredo':


[root@GPWS ~]# ifconfig teredo
teredo: flags=43 metric 0 mtu 1500
        options=80000
        inet6 fe80::ffff:ffff:ffff%teredo prefixlen 64 scopeid 0xb 
        inet6 2001:0:5ef5:79fb:4e9:5e1b:2ba5:360b prefixlen 128 
        nd6 options=3
        Opened by PID 93528


You should now be able to ping6 any IPv6-enabled host on the internet.


[root@GPWS ~]# ping6 www.google.ch
