FRITZ!Box 5490 Service - Knowledge Base
Support for VPN connections with Windows Phone
VPN (Virtual Private Network) technology allows you to establish secure network connections over the Internet between several FRITZ!Boxes or computers using FRITZ!VPN, Android devices, iOS devices, and a FRITZ!Box.
Since the FRITZ!Box supports the standardized IPSec method, as a rule you can also use it with VPN solutions from other manufacturers. However, the FRITZ!Box does not support the IKEv2 protocol used by Windows Phone 10 / 8.1 for VPN connections. Therefore, it is currently not possible to establish a VPN connection to the FRITZ!Box with Windows Phone.
