Fix L2TP and PPTP VPNs on Windows Vista/7/8/2008/R2/2012/2016/2019

On your Windows Vista, 7 or 8 client machine change or add the following registry item:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgent

New DWORD (32-bit) Value:

AssumeUDPEncapsulationContextOnSendRule

Set the value to 2

This allows the client or server to be behind a NAT firewall.

Reboot after making the change, and retry the connection.
