Setting up a VPN connection to FRITZ!Box in Android

Through VPN (Virtual Private Network), you can use the Internet connection of your Android device (for example a smartphone, tablet) to establish secure network connections to your FRITZ!Box and to the network devices and services in the FRITZ!Box home network.

In addition, whenever a VPN connection is active, all Internet queries are routed over the FRITZ!Box. This means that you will have tap-proof und tamperproof access to all web services, such as e-mail and online banking, with your Android device, even when using public wireless hotspots.

Note:In this guide we show you how to set up a VPN connection to the FRITZ!Box using Android 6.0.1 ("Marshmallow"). If you have further questions on VPN connections in Android, contact the manufacturer of your Android device directly.

Requirements / Restrictions

  • Android 4.0 or later is installed on the Android device.
  • The FRITZ!Box must obtain a public IPv4 address from the Internet service provider.

    Important:The FRITZ!Box is not accessible from the Internet over IPv4 when used on a DS-Lite ("Dual-Stack Lite") connection. When DS-Lite is active, the status "IPv4 over DS Lite" is displayed under "Connections" on the "Overview" page of the FRITZ!Box user interface.

Important:Some of the settings described here are only displayed if the advanced view is enabled in the user interface. The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS.

1 Preparations

Setting up MyFRITZ!

With MyFRITZ! you can even access your FRITZ!Box over the Internet at all times if its public IP address changes on a regular basis, for example after being automatically disconnected by your Internet service provider:

Note:If you already use a different dynamic DNS service, you can also use this service instead of MyFRITZ!.

Adjusting the FRITZ!Box's IP network

No VPN communication can occur if the Android device uses an IP address from the IP network of the FRITZ!Box. This is the case, for example, when the Android device is connected to a FRITZ!Box over wireless LAN and the IP settings of the FRITZ!Boxes were not changed (IP address 192.168.178.1 in the factory settings). Therefore, adjust the IP network of the FRITZ!Box:

Example:
In this guide, the FRITZ!Box uses the IP address 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 the "IPv4 Addresses" button.
  5. Enter the desired IP address and subnet mask.
  6. Click "OK" to save the settings.

2 Setting up a VPN connection in the FRITZ!Box

In the FRITZ!Box, set up a different user for each VPN connection.

  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, if you have not configured any users yet:
      • Click the "Add User" button and enter a name and password of your choice for the user in the corresponding fields.

        Important:Do not use any special characters, letters with umlauts, ß or accented letters in the name as Android does not process them correctly. Only use standard Latin letters (not letters such as ä, ë, ö, ü, á, é, í) and numbers.

  4. Enable the option "VPN".
  5. Click "OK" to save the settings.

Now the FRITZ!Box sets up the VPN rights for this FRITZ!Box user.
A window displaying the VPN settings for the FRITZ!Box user will then open automatically.

Note:You can call up the window any time by clicking "Show VPN Settings" in the settings for the FRITZ!Box user.

3 Setting up a VPN connection in Android

  • Set up the VPN connection on the Android device using the VPN settings displayed in the FRITZ!Box user interface for the FRITZ!Box user:

    Note:You can call up the VPN settings if you select "System > FRITZ!Box Users" in the user interface, call up the settings for the user, and click "Show VPN Settings".
