Fortinet fortigate-60r Installation Instruction

Add the following registry value to this key:

Value Name: ProhibitIpSec

Data Type: REG_DWORD

Value: 1

Save your changes and restart the computer for the changes to take effect.
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.

Start the dialup connection that you configured in the previous procedure.

Enter your L2TP VPN User Name and Password.

Select Connect.

In the connect window, enter the User Name and Password that you use to connect to 
your dialup network connection.
This user name and password is not the same as your VPN user name and password.
