 This guides walks through the setup of `Tunnelbroker.net <https://www.tunnelbroker.net/>`_ for an IPv6 Tunnel.
 
 Prerequisites
-^^^^^^^^^^^^^
+=============
 
 - A public IP address.  This does not necessarily need to be static, but you will need to update the tunnel endpoint when/if your IP address changes, which can be done with a script and a scheduled task.
 - An account at `Tunnelbroker.net <https://www.tunnelbroker.net/>`_.
 - Requested a "Regular Tunnel".  You want to choose a location that is closest to your physical location for the best response time.

 Unlike IPv4, IPv6 is really not designed to be broken up smaller than /64.  So if you ever want to have multiple LANs, VLANs, DMZ, etc, you'll want to ignore the assigned /64, and request the /48 and use that.

 Multiple LAN/DMZ Setup

 In this, you use the `Routed /48` information. This allows you to assign a different /64 to every interface, LAN, or even device.  Or you could break your network into smaller chunks like /56 or /60.

 Firewall

 Finally, don't forget the :ref:`firewall`.  The usage is identical, except for instead of `set firewall name NAME`, you would use `set firewall ipv6-name NAME`.
