FRITZ!Box Accessibility with Changing Public IPv4 Address
For VPN connections, it must be possible to reach your FRITZ!Box from the internet at all times. If the FRITZ!Box obtains its public IPv4 address from the internet provider, then the IPv4 address will generally change with each assignment.
With the MyFRITZ! service or another dynamic DNS service, the FRITZ!Box can always be reached from the internet, even when the public IPv4 address changes.
Using a MyFRITZ! Account
If you want to use MyFRITZ!, then create a MyFRITZ! account or use an existing MyFRITZ! account. Register the FRITZ!Box with the MyFRITZ! account. Upon registration, the FRITZ!Box receives a MyFRITZ! domain name. Determine the MyFRITZ! domain name.
Note:You can register multiple FRITZ!Boxes with a single MyFRITZ! account. Each FRITZ!Box receives its own MyFRITZ! domain name.
