FRITZ!Box 7340 – Service

Setting up a IPv6 subnet in the FRITZ!Box

You can use a router with its own IPv6 subnet in the FRITZ!Box home network. In this case, you do not need to configure static routes for the IPv6 subnet because the FRITZ!Box and the IPv6 router automatically exchange all of the necessary routing information.

Requirements / Restrictions

  • The FRITZ!Box must obtain an IPv6 prefix longer than 64 bits (for example /60 or /56) when it connects to the Internet.

    Note:The The IPv6 prefix is displayed in the FRITZ!Box user interface under "Internet > Online Monitor" in the line "Internet, IPv6".

Important:Some of the settings described here are only displayed if the advanced view is enabled in the user interface. The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS

1 Configuring the FRITZ!Box

  1. Click "Home Network" in the FRITZ!Box user interface.
  2. Click "Network" in the "Home Network" menu.
  3. Click on the "Network Settings" tab.
  4. Click "IPv6 Addresses".
  5. Enable the options "Enable DHCPv6 server in the FRITZ!Box for the home network" and "Assign DNS server, prefix (IA_PD) and IPv6 address (IA_NA)" in the "DHCPv6 Servers in the Home Network" section.
  6. Click "OK" to save the settings.
  7. Enable the option "Allow IPv6 prefixes announced by other IPv6 routers in the home network" in the "Additional IPv6 Routers in the Home Network" section.
  8. Click "Apply" to save your settings.

2 Configuring the IPv6 router

  • Configure the IPv6 router so that it requests its own prefix from the FRITZ!Box using IPv6 prefix delegation and that it announces its routing information to the FRITZ!Box via router advertisement.

    Note:You can find information on configuring the IPv6 router in its manual, or consult its manufacturer directly.

The router is now configured for use with its own IPv6 subnet and receives a /62 prefix from the FRITZ!Box using DHCPv6 prefix delegation.
