Setting up an IPSec VPN to the FRITZ!Box in macOS

IPSec allows you to establish VPN connections to the FRITZ!Box on your computer with macOS. This way you can access your FRITZ!Box and all devices in your home network with your computer over a securely encrypted connection, even when you are away from home.

You can find an overview of additional VPN connection options in our guide VPN with FRITZ!.

Example values used in this guide

In this guide we show you how to connect a computer with macOS 11.0.1 to the FRITZ!Box over IPSec VPN. When setting up the connection, replace the values used in this guide with your actual values.

Requirements / Restrictions

  • macOS 10.6 or later is installed on the computer.
  • The FRITZ!Box must either obtain an IPv6 address or a public IPv4 address from the internet service provider.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Preparations

Configuring MyFRITZ!

Register the FRITZ!Box with MyFRITZ! so that it can be reached on the internet at any time at a fixed MyFRITZ! address:

Setting up MyFRITZ!
  1. Click "Internet" in the FRITZ!Box user interface.
  2. Click on "MyFRITZ! Account" in the "Internet" menu.
  3. Enter your email address in the "Your email address" field.
  4. Click "Apply". Now MyFRITZ! sends you an email with the confirmation link to your FRITZ!Box.

    Important:If you do not receive an email, the email was classified as unsolicited advertising (spam). In this case, check the spam folder of your email inbox.

  5. Open the email you received from MyFRITZ!.
  6. Click the "Register Your FRITZ!Box" button in the email.

Adjusting the FRITZ!Box's IP network

Both ends of the VPN connection must have IP addresses in different IP networks. As soon as the computer is connected to a router (for example another FRITZ!Box) that uses the same IP network as your FRITZ!Box, VPN communication can no longer occur.

Note:All FRITZ!Boxes use the IP network 192.168.178.0 in the factory settings.

Set up an IP address to your FRITZ!Box that differs from the IP addresses of the routers you use to connect to the FRITZ!Box, for example 192.168.10.1 (subnet mask 255.255.255.0):

Changing the FRITZ!Box's IP network
  1. Click "Home Network" in the FRITZ!Box user interface.

  7. Click "Apply" to save the settings and on the FRITZ!Box, confirm that the procedure may be executed if asked to do so.
