FRITZ!Box 6850 LTE Service

Setting up a VPN connection to FRITZ!Box in Apple OS iOS (e.g. iPhone)

You can use VPN (Virtual Private Network) to establish a tap- and tamper-proof connection over the internet between your iPhone, iPad or your iPod touch and your FRITZ!Box. This way you can access all of the devices and data in your home network with your mobile device when you are not at home.

In addition, when a VPN connection is active, all web requests are routed over the encrypted connection to the FRITZ!Box which then resolves them over its internet connection. This means that you can use sensitive services such as email or banking in public Wi-Fi hotspots with the same peace of mind as if you were connected to your FRITZ!Box via Wi-Fi at home.

The configuration instructions given in this guide apply to iOS 13.4. For further information on VPN functions in iOS, refer to Apple.

Requirements / Restrictions

  • iOS 3.1 or later is installed on the iPhone, iPod touch or iPad.

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

Adjusting the FRITZ!Box's IP network

Both ends of a VPN connection must have IP addresses in different IP networks. VPN communication cannot occur if your iOS device is connected to a router (for example another FRITZ!Box) that uses the same IP network as your FRITZ!Box.

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

Assign an IP address to your FRITZ!Box that differs from the IP addresses of the routers used by your iOS device to connect the FRITZ!Box, for example (subnet mask

  4. Enable the option "VPN".
