IPv6 tunnel via gogo6 on Ubuntu 9.10

Posted on | March 30, 2011 | No Comments

The following is a short summary guide on making a ipv6 tunnel via http://gogonet.gogo6.com/ work on Ubuntu 9.10 Karmic Koala, for those of us who are not on 10.10 yet.

It makes no assumptions about whether tunneling instead of going generic IPv6 is a good thing to do, or whether it just makes us become lazy and put up with not having IPv6.

Also, it makes no statement about the quality of gogo6/freenet6 tunnels in comparison to other brokers like

The guide is completely based on this one – which i found just works straight forward. Thanks for sharing:

Get a freenet6 account here:

As root:

# apt-get install gw6c radvd

# /etc/init.d/radvd stop

# vi /etc/gw6c/gw6c.conf

like so:

if_prefix=eth0 (CHANGE IF NEEDED)
host_type=router (CHANGE TO host IF 1 BOX)

then do

# /etc/init.d/gw6c restart

On first attempt of starting gw6c, i m getting a short re-negotiate of broker:

root@sbut:/home/sebastian/gogoc-1_2-RELEASE# /etc/init.d/gw6c restart

).ceived a TSP redirection message from Gateway6 broker.freenet6.net

After a retry, everything is fine:

You might want to put the best gateway, in my case amsterdam.freenet6.net, into the config file above.
