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.

Important:If you do not want to route web requests via your FRITZ!Box but only want to access your FRITZ!Box and devices in the home network, you can use MyFRITZ!App to quickly and easily establish VPN connections.

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. If you are using a device that you cannot set it up on (for example Google Pixel), use MyFRITZ!App to establish the VPN connection instead.

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 mobile device 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):

  1. Click "Home Network" in the FRITZ!Box user interface.
  2. Click "Network" in the "Home Network" menu.
  3. Click on the "Network Settings" tab.
  4. Click "Additional Settings" in the section "Guest Access" to display all of the settings.
  5. Click the "IPv4 Settings" button.
  6. Enter the desired IP address and subnet mask.

    Important:Do not enter an IP address from the network 192.168.100.x. In compliance with DOCSIS, this network is reserved for the cable provider and may not be used in the FRITZ!Box.

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

2 Setting up a VPN connection in the FRITZ!Box

Set up a separate user for each VPN connection in the FRITZ!Box:

  1. Click "System" in the FRITZ!Box user interface.
  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 "Apply" to save the settings and on the FRITZ!Box, confirm that the procedure may be executed if asked to do so.
  6. Now the FRITZ!Box sets up the VPN connection for the user and opens a window with the VPN settings of the user.

    Note:You can always call up the VPN settings again by clicking "Show VPN Settings" in the settings for the user under "System > FRITZ!Box Users".
