🌐 Fritz!Box — BX/AON and XGS-PON Fibre Configuration (DHCP)

How to configure your Fritz!Box for an AON or XGS-PON fibre connection (DHCP): connection type, network parameters, IPv6 and verification.

BX/AON and XGS-PON Fibre — How does it work?

Whether you have a BX/AON line (GPON, active network) or XGS-PON (10G symmetrical), the Fritz!Box configuration is identical: direct DHCP connection, no PPPoE login, no username or password required.

The Fritz!Box must be connected directly to the optical device (ONT) provided by the fibre installer, via a fibre optic cable (fibre port).

Important: MaxiConnect lines are generally connected to plug 2 of the wall-mounted fibre optic socket.


Step 1 — Access the Fritz!Box interface

Log in to your Fritz!Box administration interface from a browser:

http://fritz.box or http://192.168.178.1

Default credentials:

Step 3 — DNS settings (optional)

By default, the Fritz!Box uses DNS servers provided automatically via DHCP. You can leave them as-is or enter custom servers:

InternetAccount InformationDNS Servers

DNSAddress
Primary DNS (e.g. Cloudflare)1.1.1.1
Secondary DNS (e.g. Google)8.8.8.8

Step 4 — Enable IPv6

  1. Go to InternetAccount InformationIPv6 tab
  2. Enable IPv6 connection and IPv6 router
  3. Select DHCPv6 for prefix assignment
  4. Click Apply

Step 5 — Verify the connection

  1. Go to Overview (home page of the interface)
  2. Check that the Internet status shows Connected
  3. The WAN IP address should be automatically assigned

If the connection is not established after 2–3 minutes, restart the Fritz!Box via SystemRestart.

Connection issues? First check that the fibre optic cable connects the fibre port of the Fritz!Box to the optical device (ONT).
