Now that the package is installed, please finish it with the following steps:

- Copy /usr/local/share/examples/freenet6/tspc.conf.sample
to /usr/local/etc/tspc.conf
- Check the values of /usr/local/etc/tspc.conf. If you have registered at
* the website, fill in your userid and password there. (If you want to browse anonymously then you don't have to change anything in config file)
- Run /usr/local/etc/rc.d/freenet6.sh to start the tunnel.
- Try to ping a IPv6 host, for example: ping6 http://www.jp.freebsd.org

Please note that tsps[12].freenet6.net are not in service anymore,
please use broker.freenet6.net instead.

Net/freenet6 now supports rc.subr.
Please add 'freenet6_enable="YES"' to your /etc/rc.conf to make it start autoamtically at startup.
