Setup and configure L2TP/IPSec-PSK VPN on Windows 8

Attention! In order to get L2TP/IPSec working correctly with Windows, it is necessary to make changes to the registry (add a parameter). This problem is listed on the official Microsoft website https://support.microsoft.com/en-us/kb/926179. This procedure will be described below in (1) of this manual. If you are not ready to make changes to the Windows registry, then you can set up VPN with PPTP protocol (see PPTP settings), which not required the modification of the registry.

1. Making changes to the Windows registry (Administrative rights):
1) Run regedit with administrative privileges and locate the section HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgent
2) Create DWORD (32 bit) parameter AssumeUDPEncapsulationContextOnSendRule and set value 2 for it.
