Route an IPv6 netblock to your local network

So far, all we've done is allocate a single IPv6 address to your machine that is hosting the tunnel. One of the nice things about IPv6 however, is the ability to obtain a large number of public IP addresses for your local networks rather than using NAT. In fact, Hurricane Electric and SixXS both offer complementary /48 networks to use with your tunnel. A /48 includes 2^80 IP addresses, or 1,208,925,819,614,629,174,706,176. Much better than the one IPv4 address you typically get from a consumer IP address. To utilize them, you just need to advertise their availability.

How to do it...

Install radvd via your package management system:

1. Configure /etc/radvd.conf:

   interface eth1
   {
      AdvSendAdvert on;
      prefix 2001:DB8:1:1::/64
      {
      };
   };

2. Start radvd via the init script or as appropriate for your distribution.

How it works…

Rather than requiring DHCP for IP address allocation (although DHCPv6 is available if desired), IPv6 implements the...
