Using a IPv6 Connection with a Tunnel Protocol: Connection Settings

You selected the setting "Use IPv6 connection with a tunnel protocol". In the connection settings you now have to select a tunnel protocol and enter any corresponding settings for it.

6to4

6to4 is a tunnel protocol that can be used by anyone. No registration is required. When the FRITZ!Box uses the 6to4 protocol, it packs IPv6 packets inside IPv4 packets and sends them to a gateway in the IPv4 range of the internet, which is the access point to the IPv6 range of the internet. The IPv4 address of the FRITZ!Box is rendered on an IPv6 address space according to a prescribed mechanism. This means that every change to the IPv4 address also changes the IPv6 address space of the FRITZ!Box. The IPv4 packets, each of which contains one IPv6 packet, are sent to a gateway that unpacks the IPv6 packets and forwards them to the IPv6 range of the internet.

SixXS

You must apply for a SixXS tunnel with Heartbeat support at http://www.SixXS.net. SixXS offers Internet users a free tunnel protocol for access to the IPv6 range of the Internet.

  1. Register with SixXS as a user.
  2. Then apply for the tunnel with Heartbeat support.
  3. Apply for a SixXS subnet so that each of the network devices in your local network can be assigned its own IPv6 address.
  4. Enter the account information you received from SixXS in the appropriate fields.

6RD

The 6RD tunnel protocol is based on the 6to4 tunnel protocol. In contrast to 6to4, in 6RD the packed IPv4 packets are always sent to the same gateway, which then packs the IPv6 packets and forwards them to the IPv6 range of the internet. Use these tunnel settings if your IPv4 internet service provider offers a 6RD gateway.

  1. Request the IPv4 address of the 6RD gateway, the IPv6 prefix and the IPv4 mask length from your IPv4 internet provider.
  2. Enter the requested values in the "IPv4 address of the tunnel end-point", "IPv6 prefix" and "IPv4 mask length" fields.

6in4

The 6in4 tunnel protocol can be used if your IPv4 internet provider offers a gateway for unpacking the IPv6 packets. In contrast to 6RD, here you must make all entries manually.

  1. Request the IPv4 address and the IPv6 address of the 6in4 gateway from your IPv4 internet provider.
  2. Request the local IPv4 address for the FRITZ!Box and the IPv6 prefix from your IPv6 internet provider.
  3. Enter the values in the "IPv4 address of the tunnel end-point", "IPv6 address of the tunnel end-point", "Local IPv6 address" and "IPv6 prefix" fields.
