This software allows you to create and maintain an IPv6 tunnel if you don't have native IPv6 connectivity. If you wish to maintain a static IPv6 address, you *must* register a Freenet6 account and edit /etc/gogoc.conf with the account you configured. Information on the Freenet6 tunnelbroker and a link to the registration process is at http://gogonet.gogo6.com/page/freenet6-tunnelbroker
