The default Windows 2000 L2TP traffic policy does not allow L2TP traffic without IPSec encryption. You can

to the Microsoft documentation for editing the Windows Registry.
•
Use the registry editor (regedit) to locate the following key in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Rasman\Parameters
•
Add the following registry value to this key:
Value Name: ProhibitIpSec
Data Type: REG_DWORD

You must add the ProhibitIpSec registry value to each Windows 2000-based endpoint computer of an
L2TP or IPSec connection to prevent the automatic filter for L2TP and IPSec traffic from being created.
When the ProhibitIpSec registry value is set to 1, your Windows 2000-based computer does not
create the automatic filter that uses CA authentication. Instead, it checks for a local or Active Directory
IPSec policy.
