FRITZ!Box 7390 – Service

Setting up dynamic DNS in the FRITZ!Box

With dynamic DNS, you can always access applications and services for which you configured port sharing in the FRITZ!Box (for example Microsoft Remote Desktop) at a fixed domain name from the Internet at all times, even though the public IP address of the FRITZ!Box changes on a regular basis.

Note:You can also use MyFRITZ! to access your FRITZ!Box and the home network safely and conveniently from the Internet at any time.

Requirements / Restrictions

  • Dynamic DNS is not available if the FRITZ!Box shares the Internet connection of another router ("IP client mode", "wireless repeater"). In this case, configure dynamic DNS in the other router.
  • The FRITZ!Box must obtain a public IPv4 address or an IPv6 address from the Internet service provider.

    Important:The FRITZ!Box is only accessible from the Internet over IPv6 when used on a DS-Lite ("Dual-Stack Lite") connection. When DS-Lite is active, the status "IPv4 over DS Lite" is displayed under "Connections" on the "Overview" page of the FRITZ!Box user interface.

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 Setting up dynamic DNS

  1. Click "Internet" in the FRITZ!Box user interface.
  2. Click "Permit Access" in the "Internet" menu.
  3. Click on the "Dynamic DNS" tab.
  4. Click the (Help) icon on the top right.
  5. Configure the dynamic DNS domain name as described in the FRITZ!Box help.
  6. Click "Apply" to save your settings.

Now the FRITZ!Box will transmit its current IP address to the Dynamic DNS provider each time it connects to the Internet so that the FRITZ!Box can always be contacted via its distinct dynamic DNS domain name.
