Windows Phone 8.1 L2TP-VPN server behind NAT RRS feed

  • Question

  • Hello,

    I have a working VPN server at home based on L2TP. With Windows Phone 8.1 I can connect to the VPN if the smartphone is on the same internal network. Otherwise (outside the LAN, on Internet) I can't connect through NAT to the VPN server.

    Apple devices works fine. Also Windows clients works fine, only when I make a registry change explained here: http://support2.microsoft.com/kb/926179/en-us.

    What is the reason why this not turned on by default, like other OS's? It's technically possible.
