Setting up the FRITZ!Box as a cascaded router

When the FRITZ!Box is used as a cascaded router, it shares the existing Internet connection of your other router, but it still provides its own network that is separate from the other router. In this case

  • the firewall of the FRITZ!Box is enabled.
  • network devices (for example computers, smartphones) connected to the FRITZ!Box no longer obtain their IP settings from the other router; instead, they obtain them from FRITZ!Box.

Requirements / Restrictions

  • Devices connected to the FRITZ!Box cannot be accessed from the network of the other router.
  • You cannot use MyFRITZ!.
  • Depending on the other router, functions that require a public IP address - such as port sharing and receiving incoming VPN connections - are either not be usable, or only usable to a limited extent.
  • The FRITZ!Box and the other router must use different IP networks.

    Note:If the FRITZ!Box's IP settings are the factory settings, then they are automatically adjusted when you configure the connection over LAN (IP network: 192.168.188.0, subnet mask: 255.255.255.0).

Note:The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS for your FRITZ!Box.

1 Configuring the FRITZ!Box

  1. Click "Internet" in the FRITZ!Box user interface.
  2. Click "Account Information" in the "Internet" menu.
  3. Select "Other Internet service provider" from the drop-down list "Internet service provider". With some regional settings, this entry will not be displayed until you select "More Internet service providers".
  4. Enable the option "External modem or router" in the "Connect via" or "Connection" section.
  5. Enable the option "Establish own connection to the Internet" in the "Operating Mode" section.
  6. Enable the option "No" in the "Account Information" section.
  7. Enter the relevant speeds of your Internet connection in the "Downstream" and "Upstream" fields.

    Example:
    Enter 32000 for a downstream of 32 Mbit/s; enter 2000 for an upstream of 2 Mbit/s.

  8. Click on "Change connection settings".
  9. Configure the IP settings:
    • If the other router provides a DHCP server:
      • Enable the option "Obtain the IP address automatically (DHCP)".
    • If the other router does not provide a DHCP server:
      1. Enable the option "Configure the IP address manually".
      2. Enter IP settings that fit with the IP network of the router:
        • "IP address": IP address from the router's network.

          Example:
          The router has the IP address 192.168.100.1 (subnet mask 255.255.255.0) and is therefore in the network 192.168.100.0. In this case you can enter 192.168.100.2 as the IP address.

          Important:The IP address you select may not already be used by another device in the router's network.

        • "Subnet mask": Subnet mask of the router
        • "Default gateway": IP address of the router
        • "Primary DNS server": IP address of the router
  10. Click "Apply" to save your settings.

2 Connecting the FRITZ!Box with the network

  • Use a network cable (for example the yellow network cable included with delivery) to connect the "LAN 1" port on FRITZ!Box directly to the router, or connect it by means of a hub or switch.

Now the FRITZ!Box uses the Internet connection of the other router.

3 Opening the FRITZ!Box user interface

Enter http://fritz.box as usual to call up the user interface with network devices connected to the ports "LAN 2" through "LAN 4" or to the FRITZ!Box's wireless network.

Proceed as follows to open the user interface with network devices connected to the other router and not to the FRITZ!Box:

  1. In the web browser, enter the IP address that the other router's DHCP server assigned to the FRITZ!Box (for example 192.168.100.20),
    • or, if you enabled the option "Configure the IP address manually" in the FRITZ!Box,
      • in the web browser, enter the IP address that you entered in the "IP address" field in the FRITZ!Box user interface (for example 192.168.100.2).
  2. In the corresponding fields, enter the user name and password of a FRITZ!Box user who is authorized to access the FRITZ!Box from the Internet and click "Log in".

    Note:You can edit the access rights of FRITZ!Box users under "System > FRITZ!Box Users" in the user interface. This guide contains further information on FRITZ!Box user accounts.

4 Setting up the FRITZ!Box to conduct calls over another router

The following step is only necessary if you would like to connect telephones to the FRITZ!Box and then use the Internet connection of the other router or a landline to conduct calls with them:
