This describes how to configure your Windows 10 device to connect to the Foxpass VPN.
Follow these directions, entering in your VPN's PSK and Public IP where appropriate.
After you've added the connection, right click it and select Properties. Then, under the Security tab, make sure that the "Unencrypted password (PAP)" box is checked.
Then, log in using your Foxpass username and password.
Note: If the above doesn't work, you may need to modify the Windows registry (add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgent\ AssumeUDPEncapsulationContextOnSendRule=2) as discussed here.
