Configuring a VPN Connection for Windows

A VPN connection for a Windows computer to the FRITZ!Box is set up with the "Configure FRITZ!Box VPN Connection" software. The Windows computer needs the "FRITZ!VPN" program as a VPN client. Both programs can be downloaded from the AVM website.

Prerequisite: Windows Version

One of the following Windows version is installed on the computer:

  • Windows 10 (64-bit)
  • Windows 8.1 (64-bit)
  • Windows 8 (64/32-bit)
  • Windows 7 (64/32-bit)

Prerequisite: Public IPv4 Address

The FRITZ!Box must obtain a public IPv4 address from the internet service provider.

Check whether FRITZ!Box obtains a public IPv4 address: Determining the Public IPv4 Address of the FRITZ!Box.

Making FRITZ!Box Accessible 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.

Adjusting the IPv4 Networks on the Ends of the VPN Connection

Both ends of a VPN connection must have IPv4 addresses in different IPv4 networks. Only then is VPN communication possible.

Note:Upon delivery, every FRITZ!Box uses the IPv4 network 192.168.178.0.

When both ends of the VPN network have a FRITZ!Box used for internet access, then at least one of the FRITZ!Boxes must have an IPv4 network different from the factory settings.

  • When using mobile devices, it is not predictable which device will be used to connect the internet. Any public wireless network may have a FRITZ!Box behind it. Change the IPv4 network of the FRITZ!Box when you configure VPN connections for network devices.
  • When you configure a VPN connection for two FRITZ!Box networks, then change the IPv4 network in each FRITZ!Box.
