Setting up a VPN to the FRITZ!Box in Android

Via VPN (Virtual Private Network), you connect your Android smartphone or tablet with your FRITZ!Box over a secure, encrypted connection. This allows you to access your FRITZ!Box and all of the devices in your home network with your mobile device even when you are away from home.

In addition, the device also forwards all web requests over the VPN connection to your FRITZ!Box. This means you can use sensitive services such as email or online banking in public Wi-Fi hotspots just as securely as if you were directly connected to your FRITZ!Box via Wi-Fi at home.

Requirements / Restrictions

  • Android 4 or later is installed on the mobile device. In Android 12, it is not possible to set up VPN connections to the FRITZ!Box with all manufacturers (for example with Google Pixel).

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

1 Preparations

Setting up dynamic DNS

  1. Set up dynamic DNS in the FRITZ!Box.

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 mobile device is connected to a router (for example another FRITZ!Box) that uses the same IP network as your FRITZ!Box, VPN communication is no longer possible.

Note:All FRITZ!Boxes use the IP network 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 (subnet mask

  1. Click on "Home Network" in the FRITZ!Box user interface.
  2. Click on "Home Network Overview" in the "Home Network" menu.
  3. Click on the "Network Settings" tab.
  4. Click on the "IPv4 Addresses" button. If the button is not displayed, enable the Advanced View first.
  5. Enter the desired IP address and subnet mask.
  6. Click on "OK" to save the settings.

  2. Click "FRITZ!Box Users" in the "System" menu.
  3. Click the (Edit) button for the user who intends to connect to the FRITZ!Box via VPN or set up a new user for the VPN connection:
    1. Click the "Add User" button.
    2. Enter a name and password for the user in the corresponding fields.
  4. Enable the option "VPN".
  5. Click "OK" to save the settings.
  6. Now the FRITZ!Box sets up the VPN connection for the user and opens a window with the VPN settings of the user.
